1b22574ddb cmd/godoc: fix expected test output for Go 1.8 and older
A go/build change in Go 1.9 (CL 33158) allowed for a better expected
error message for "nonexistingpkg" case. CL 37768 did that. However,
that shouldn't be done for Go 1.8 and older, since they don't have
the corresponding go/build change.

So, if the version is Go 1.8 or older, allow matching those previous
expected outputs (before CL 37768) for "nonexistingpkg" case.

Move test cases for TestCLI from a package-level variable into TestCLI
itself. This is more readable, and isGo19's value is ready in time.

Fixes golang/go#20122.

518248cfad cmd/compilebench: add -pkg flag to compile a single package
Sometimes, as with CL 41493, or when investigating
a reported issue, there's a package of interest
that is not part of the standard compilebench suite.
Add a -pkg flag to allow easy access to the compilebench
set of goodies (allocs, object file stats) without
having to edit and reinstall compilebench itself,
which is what I have been doing.

9bf174b4d3 cmd/stringer: use source importer when available
This means that running stringer should always
have the intended effect, without having to
go install the package first, which was a common
source of confusion.

The source importer is marginally slower,
but stringer is run infrequently,
and we're only typechecking one package (and fmt),
not an entire tree, as vet does.

Fixes golang/go#10249

ef3dcd5937 cmd/heapview: look for tools repository in all GOPATH entries
The GOPATH environment variable is defined at
https://golang.org/cmd/go/#hdr-GOPATH_environment_variable as:

> The GOPATH environment variable lists places to look for Go code. On
> Unix, the value is a colon-separated string. On Windows, the value is
> a semicolon-separated string. On Plan 9, the value is a list.

It is legal for Go packages to be in any of those places, not only
the first entry. Look in all places for golang.org/x/tools repository.

Cache the directory that is found. It's slightly more expensive
to look for it, since potentially multiple directories must be
checked for existence.

Updates golang/go#19400.

37a1062ad0 cmd/tip: redirect http://tip.golang.org to https
At some point we switched tip.golang.org to run in GKE, which
terminates TLS directly on port 443. This requires a new technique
for detecting a plain HTTP connection. In addition we may want to run
talks.golang.org on App Engine Flex, which uses an X-Forwarded-Proto
header to indicate HTTP, so let's prepare for that possibility.

7fdb908ead cmd/guru: fix tests now that go1.9 go/types returns fake packages
The go1.9 type checker now returns fake packages in addition to an
error if the package was not found at all.  This changes the behavior
of guru in a release-specific way, requiring the test to be split into
a common part and a go1.9-specific part.

In hindsight, perhaps it would have been better to place the
expectation in a comment alongside the query so that they can be
easily enabled or disabled together.  (The downside of that design is
that you can't batch-update all the expectations to match the actual
behavior.)

f595fb5c96 cmd/godoc, godoc: implement build.Context.IsDir, update expected error string
Prior to this change, handlerServer.GetPageInfo created a build.Context
starting with build.Default, and provided custom implementations for
its IsAbsPath, ReadDir, and OpenFile funcs. Those funcs would operate
on h.c.fs virtual filesystem.

https://godoc.org/go/build#Context.IsDir is documented as:

	// IsDir reports whether the path names a directory.
	// If IsDir is nil, Import calls os.Stat and uses the result's IsDir method.
	IsDir func(path string) bool

IsDir was left as nil, and so the default implementation was used.
The default implementation uses os.Stat and isn't aware of the h.c.fs
virtual filesystem.

This appears to have been harmless in the past, but after the change to
go/build in https://golang.org/cl/33158, it started to interfere with
the operation of godoc. The command godoc began to fail to resolve
relative import path "." in directories that exist, because the
incorrect IsDir implementation was looking in real filesystem, rather
than the virtual one:

	$ ./godoc fmt
	2017/03/04 18:59:50 cannot find package "." in:
		/target
	$ ./godoc -http=localhost:6060
	2017/03/04 19:00:07 cannot find package "." in:
		/src/fmt

Providing a custom implementation of IsDir that is aware of the h.c.fs
virtual filesystem, and performs a stat operation on the correct path
there resolves that problem. It also fixes the failing tests.

Additionally, because the exact error string returned from
Context.Import has changed after https://golang.org/cl/33158,
and now contains the text "package not found" rather than the
underlying error text from filesystem caused by a failed ReadDir
operation, the expected error message from "./godoc nonexistingpkg"
in a test needed to be updated to "cannot find package". It's no longer
dependent on the operating system.

It might be desirable to provide more relevant detail in the error
message from cmd/godoc when a package is not found, but that should be
determined and done in a followup CL. The scope of this one is to fix
normal functionality.

This change follows update to go/build in https://golang.org/cl/33158.

Helps golang/go#19401.

8e779ee0a4 x/tools/cmd/gotype: support type checking of xtest packages.
As noted by griesemer in golang/go#18799, this doesn't address the issues
raised in golang/go#11415 because when checking an xtest package the
corresponding package is assumed to have been installed. This
however is similar to the assumptions made by go vet (raised
as an issue in golang/go#16086). So whilst not perfect, it will probably
suffice until golang/go#11415 is resolved.

- go/ssa/interp: add 'mono' result to time.now intrinsic
- go/gcimporter15/bimport.go: make consistent with the version in gc
- go/ssa/interp: update test error message
- go/ssa: update a comment

The go/gcimporter15/bexport.go logic is stale and needs to be brought
up to date.  Needs a separate CL since it's tricky.

Tested on go1.6, go1.7, go1.8.

- always display the value of a constant expr, whether query expr is a
  definition, a reference, or an alias.
- eliminate some go1.5 portability code.
- remove go1.8 fork of referrers; no changes are necessary
  since I decided not to treat aliases specially.
- add tests.

8e53eb937b go/ssa: support custom TestMain functions in test packages
Supporting user-defined TestMain functions requires that we generate a
"testmain" package for each testable package, rather than a single one
for the entire program.  This entails these API changes:

1. (*ssa.Program).{CreateTestMainPackage,FindTests} both now
   accept only a single package.  Existing clients that pass them
   multiple packages must call them from a loop.

2. (*ssa.Program).FindTests returns an additional result, the the
   optional TestMain *ssa.Function.  Existing clients may discard it.

Also:
- Test the new logic using the SSA interpreter
- add ssautil.MainPackages helper
- callgraph: allow multiple main packages, and analyze them all
- ssadump -run: allow multiple main/test packages, and run each in a new interpreter
- minor simplifications to some callers (e.g. guru)

053ddb97bf x/tools/cmd/heapview: add basic client serving
This change primarily exists to import Typescript and the
ES6 module loader polyfill as dependencies for this project.
Both dependencies are relatively lightweight and can be easily
removed if we decide we don't need them.

The module loader polyfill implements support for an upcoming
browser feature in ES6 (the next version of JavaScript). This
feature helps modularize Javascript code and conveniently split it
into multiple files. It should be supported by the stable versions
of the four major browsers (Chrome, Firefox, Safari and Edge)
by the end of the year. Once that happens, we can remove the polyfill.

The Typescript compiler provides two things: First, it compiles
new, but not-yet-supported ES6 Javascript features into ES5. It
also provides a typechecker similar to what Closure does, but types
are indicated in syntax rather than JSDoc comments. If we decide
we don't want this dependency, we can compile the Typescript code
into human-readable JavaScript code. (The compiler basically
strips out types and replaces ES6 language features with more
well-supported JavaScript equivalents). The Typescript compiler
is not required for development. typescript.js and a feature in
the module loader will be used to compile Typescript into JavaScript
at serving time. (We might want to do something different for the
production version, but we can get to that later).

The change also adds code to serve the HTML and Javascript files.

This brings goimports from 160ms to 100ms on my laptop, and under 50ms
on my Linux machine.

Using cmd/trace, I noticed that filepath.Walk is inherently slow.
See https://golang.org/issue/16399 for details.

Instead, this CL introduces a new (private) filepath.Walk
implementation, optimized for speed and avoiding unnecessary work.

In addition to avoid an Lstat per file, it also reads directories
concurrently. The old goimports code did that too, but now that logic
is removed from goimports and the code is simplified.

This also adds some profiling command line flags to goimports that I
found useful.

Updates golang/go#16367 (goimports is slow)
Updates golang/go#16399 (filepath.Walk is slow)

e047ae774b cmd/goimports, imports: make goimports great again
I felt the burn of my laptop on my legs, spinning away while processing
goimports, and felt that it was time to make goimports great again.

Over the past few years goimports fell into a slow state of disrepair
with too many feature additions and no attention to the performance
death by a thousand cuts. This was particularly terrible on OS X with
its lackluster filesystem buffering.

This CL makes goimports stronger, together with various optimizations
and more visibility into what goimports is doing.

* adds more internal documentation

* avoids scanning $GOPATH for answers when running goimports on a file
  under $GOROOT (for Go core hackers)

* don't read all $GOROOT & $GOPATH directories' Go code looking for
  their package names until much later. Require the package name of
  missing imports to be present in the last two directory path
  components.  Then only try importing them in order from best to
  worst (shortest to longest, as before), so we can stop early.

* when adding imports, add names to imports when the imported package name
  doesn't match the baes of its import path. For example:
        import foo "example.net/foo/v1"

* don't read all *.go files in a package directory once the first file
  in a directory has revealed itself to be a package we're not looking
  for. For example, if we're looking for the right "client" for "client.Foo",
  we used to consider a directory "bar/client" as a candidate and read
  all 50 of its *.go files instead of stopping after its first *.go
  file had a "package main" line.

* add some fast paths to remove allocations

* add some fast paths to remove disk I/O when looking up the base
  package name of a standard library import (of existing imports in a
  file, which are very common)

* adds a special case for import "C", to avoid some disk I/O.

* add a -verbose flag to goimports for debugging

On my Mac laptop with a huge $GOPATH, with a test file like:

	package foo
	import (
	       "fmt"
	       "net/http"
	)

	/*

	*/
	import "C"

	var _ = cloudbilling.New
	var _ = http.NewRequest
	var _ = client.New

... this took like 10 seconds before, and now 1.3 seconds. (Still
slow; disk-based caching can come later)

Updates golang/go#16367 (goimports is slow)
Updates golang/go#16384 (refactor TestRename is broken on Windows)

50ff896a1c cmd/guru: definition: opt: avoid type checker for qualified identifiers
For a 'definition' query on X in p.X, use special logic to load and
parse package p and find the declaration of package member X, without
using the type checker.  Such queries now typically take under
10ms (faster than godef).

The logic assumes that import "something/p" defines the name p.  If this
assumption is false, p.X could be a selection of a field or method X on
a member p of the same package, defined in another file.
So don't write code like that.

Added missing test of 'definitions'.
JSON tests now sanitize absolute $GOPATH filenames in the output.

9ae7e1769c cmd/guru: Emacs: run guru asynchronously using compilation-mode
We define a derived mode of compilation-mode, so that various
names say "guru" instead of "compilation", and use the hooks it
provides to apply our postprocessing incrementally instead of
all at the end.  It's much faster, and works nicely with the
new streaming referrers query.

Compilation mode requires a shell command, not an execve array,
so go-guru--compile-command joins the arguments with spaces.
go-guru--exec has been specialized for JSON mode,
and renamed to go-guru--json.

go-guru--set-scope-if-empty is now done by each mode, to avoid
the NEED-SCOPE parameter to go-guru--exec.

Visible changes:
- "referrers" queries now emit a stream of results,
  so they start appearing quickly even in large queries.
  We no longer report the total number of matches.
- packageReferrers now also uses AfterTypeCheck hook and streaming.
- XML support has been dropped.
- The -format flag has been replaced by -json.

JSON protocol changes:
- The enclosing Result struct has been removed.
- Likewise the 'mode' field (since the caller knows it already)
- "freevars" and "referrers" now emit a stream of objects
  In the case of referrers, the first object has a different from the rest.
- The "referrers" results include the text of the matching line
  (parity with -json=false)

Implementation details:
- the concurrency-safe q.Output function can be called
  many times, each with a queryResult to print.
- fset is no longer saved in Query (cleaner)
- queryResult methods renamed PrintPlain, JSON

2336c53cf0 cmd/guru: compute referrers as packages are type checked
This CL makes little observable difference to the behavior but paves the
way for streaming 'referrers' and (later) 'implements' queries which
scan the entire workspace, but print each result as soon as it is found.

The go/loader package now exposes a hook, AfterTypeCheck, that lets
clients inspect each package as soon as it is type-checked, and also
modify it, for instance to release unneeded data structures.

A 'referrers' query applied to an exported object must scan the entire
workspace.  It uses this hook so to gather uses of the query object in
streaming fashion.  However, for now, it still accumulates the results
and prints them all at the end, though I propose to change that in a
follow-up.

Code details:
- The referrers logic had a 2-iteration loop to load first the query
  package and then if necessary the enlarged program.  The second
  iteration has now been unrolled and split into globalReferrers.
- Queries for package names (whether in a package declaration or
  a qualified identifier) have been split off into packageReferrers.
  It now loads all direct importers of the query package,
  which catches some references that were missing before.
  (It used to inspect only the forward dependencies of the query
  package.)

Also:
- Referrers.Pos (the position of query identifier) was removed from the
  JSON output.  It's a nuisance to compute now, and it's already
  absent from the plain output.
  (In a follow-up, I plan to simplify the information content of the
  JSON output exactly what is currently printed in the plain output.)

2327a65811 cmd/guru: fix tests
A consequence of CL 19747 was that ad hoc packages of a single filename
are no longer valid -scope arguments, which broke most of the tests.

This CL fixes the tests by extracting the import path from the filename.
The test output now includes the import path, not the package
name, of each of these packages, so the output was updated too.

Also, the -scope argument caused the main package to be imported twice,
once as main.go and once under its import path, causing duplicate
'implements' results.

I'm not sure how I failed to notice this.

bf084ef758 imports: add support for vendor directories
Editor modes that invoke the goimports command on temporary copies
of actual source files will need to invoke goimports -srcdir now to say
where the real source directory is. Otherwise goimports will not consider
vendored or internal packages when looking for new imports.

In lieu of a test for cmd/goimports (because it has no tests),
a command transcript:

	$ cd /tmp
	$ cat x.go
	package p
	var _ = hpack.HuffmanDecode
	$

	$ GOPATH= goimports < x.go
	package p

	var _ = hpack.HuffmanDecode
	$ GOPATH= goimports x.go
	package p

	var _ = hpack.HuffmanDecode
	$

But with the new flag:

	$ GOPATH= goimports -srcdir $GOROOT/src/math < x.go
	package p

	import "golang.org/x/net/http2/hpack"

	var _ = hpack.HuffmanDecode
	$ GOPATH= goimports -srcdir $GOROOT/src/math x.go
	package p

	import "golang.org/x/net/http2/hpack"

	var _ = hpack.HuffmanDecode
	$

The tests in this CL and the above transcript assume that
$GOROOT/src/vendor/golang.org/x/net/http2/hpack exists.
It did in 40a26c9, but it does not today.
It will again soon (once Go 1.7 opens).

For golang/go#12278 (original request).

d0c9d43af1 bundle: new docs, command-line interface
Before, "bundle -help" printed only one not particularly useful line:

	Usage of bundle:

and "bundle" printed a bit more but not a standard usage message:

	bundle: Usage: bundle package dest prefix

	Arguments:
	 package is the import path of the package to concatenate.
	 dest is the import path of the package in which the resulting file will reside.
	 prefix is the string to attach to all renamed identifiers.

And most of that output belonged in (but was missing from) the doc comment,
which leaned heavily on the reader inferring usage from one example.

While fixing all this, I ended up dropping "dest" and "prefix" as required
arguments: perfectly good defaults can be inferred in the common case
where the bundle is intended for the current directory. The defaults can be
overridden with the new -dst and -prefix option.

I corrected a TODO about not assuming the package name could be
derived from the destination import path. Like -dst and -prefix, the
default package name can be inferred from the current directory,
but there is also a new -pkg option to override the default if needed.

I added a -o option to specify the destination output file (standard output
is still the default output). One benefit of -o is that it makes the bundle
commands self-contained in the sense of not needing a shell.
That in turn makes them suitable for use with "go generate", so when -o
is specified the bundle output now includes a "//go:generate" comment
for updating the bundle mechanically.

To keep bundle working for net/http's use case, I added a -importmap
option to specify additional import rewrites (net/http needs the http2
import of golang.org/x/net/http2/hpack rewritten to begin with internal/golang.org).

The net effect of all of this is that the first two lines at the top of
net/http/h2_bundle.go will change from:

	// Code generated by golang.org/x/tools/cmd/bundle command:
	//   $ bundle golang.org/x/net/http2 net/http http2

to

	// Code generated by golang.org/x/tools/cmd/bundle.
	//go:generate bundle -o h2_bundle.go -prefix http2 -import golang.org/x/net/http2/hpack=internal/golang.org/x/net/http2/hpack golang.org/x/net/http2

and net/http's copy of http2 can now be updated by "go generate"
instead of by copying and pasting commands from source code to shell.

For an experiment I am doing with cmd/dist bundling archive/zip,
the header is even shorter and makes a better demonstration of the
power of the defaults:

	// Code generated by golang.org/x/tools/cmd/bundle.
	//go:generate bundle -o zip.go archive/zip

New usage message, printed by "bundle -help" and "bundle":

	Usage: bundle [options] <src>
	  -dst path
	    	set destination import path (default taken from current directory)
	  -import map
	    	rewrite import using map, of form old=new (can be repeated)
	  -o file
	    	write output to file (default standard output)
	  -pkg name
	    	set destination package name (default taken from current directory)
	  -prefix p
	    	set bundled identifier prefix to p (default source package name + "_")

See CL for new doc comment.

Following this CL I will send a CL updating the two-line header in net/http/h2_bundle.go
to match the new usage of the bundle, whatever that ends up being.

fb3df4a89d cmd/guru: definition: try parser-based resolution first
The parser does intra-file resolution.  It's only a best-effort but
it's extremely fast, so we try it first and fall back to the loader-based
implementation if it fails.

Also:
- factor definitionResult so it doesn't depend on either go/types.Object
  or go/ast.Object.
- guessImportPath: make importPath=="" result an error,
  since you can't import the empty string.  Simplify importQueryPackage.
- Make fastQueryPos continue in face of minor parse errors.
- describe: eliminate old TODO; suppress log statement.

The -modified flag causes guru to read a simple archive file from stdin.
This archive specifies alternative contents for one or more file names.
The build.Context checks this table before delegating to the usual
behavior.

This will not work for files that import "C" since cgo accesses the
file system directly.

Added end-to-end test via Emacs.

608d57b3ae cmd/guru: call{ers,stack}: avoid pointer analysis where possible
As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:

The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.

Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph.  As a bonus, this also causes the tool to
preferentially report all-static callpaths.

A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.

The new code is covered by the existing tests.

542ffc7e75 tools: switch to standard go/types at tip
A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.

Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.

All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

a25a8d567b tools/cmd/vet: Create vet checks for examples.
In spite of https://blog.golang.org/examples and
http://golang.org/pkg/testing/#pkg-examples, a number of internal Go
authors have found writing documentation examples to be problematic in
the sense that the syntax is error-prone due to loose coupling with
identifiers found in the source corpus.

This commit introduces a suite of validations for documentation
examples:

    Overall:
    - Correct suffices, if present
    - Niladic function argument and return signatures

    func Example() {}
    func ExampleF() {}
    - F exists
    func ExampleT() {}
    - T exists
    func ExampleT_M() {}
    - T exists
    - M exists within T

Further, if the example is in `package foo_test`, vet attempts to
resolve the respective lookups in `package foo`, if `package foo`
exists (cf., `package stringutil_test`).

7d75e8b219 cmd/fiximports: a tool to rewrite import paths to match import comments.
fiximports enumerates the set of packages identified by the
command-line arguments, using "go list" notation.  Within each
package, it replaces all imports of non-canonical packages by their
canonical name, introducing an import renaming if (heuristically)
necessary.

If a package comes from one of the -baddomains, and it has no import
comment, fiximports reports an error.  The error message includes the
list of packages that import the errant package, directly or
indirectly.  This flag is used to indicate "sinking ship" package
hosting domains like code.google.com.

Caveat: this process is not trivially reversible.  Consider a package A
to which we add an import comment "B", and run the tool.  Package C,
which imported A, now imports B.  ('go get -u' would fetch package B).
But changing the import comment in directory A and re-running the tool
will not cause C to be changed because it no longer imports A; it
imports B.

ignore some other episodic failures).

Do you find it useful?
I use it for several years for all kinds of episodic failures (not just Go btw).

9c57c19a58 go/loader: eliminate ImportFromBinary option and PackageCreated hook
The loader package now loads, parses, and type-checks a whole program
from source, and that is all.

Also:
- simplified loader logic
- ssa.Create is gone; use ssautil.CreateProgram.
- ssautil.LoadPackage renamed to BuildPackage.
  It is now independent of go/types' Import hook and the Packages map.
- ssadump: -importbin flag removed.
  The value of this flag was that it caused the tool to print IR
  for only a single package; this is now the normal behaviour.

Fixes #9955

0770aced4f cmd/tipgodoc: Kill godoc process if http.ListenAndServe fails
Currently, if for some reason http.ListenAndServe fails, any running
running godoc processes don't get killed. I don't think this would ever
actually happen because, with godoc being set up in a separate go
routine, http.ListenAndServe would always(?) fail before the godoc
server started.

This change ensures that, if a Proxy has a cmd, it is closed when
http.ListenAndServe fails.

65b5a8eca7 cmd/cover: cover funcs in if, for, switch clauses
This peculiar case arose in range statements but there are other contexts
and one turned up in the auto-generated translation of the compiler.
Take care of it always.

	for i := 0; i < 0; func() {i++; q=q.Link}() { ... }

That code has been given the obvious rewrite but we should still handle it.

Odd but easy to fix (tricky to test).

Fixes #10269.

b28839e4bd oracle: several major improvements
Features:

  More robust: silently ignore type errors in modes that don't need
  SSA form: describe, referrers, implements, freevars, description.
  This makes the tool much more robust for everyday queries.

  Less configuration: don't require a scope argument for all queries.
  Only queries that do pointer analysis need it.
  For the rest, the initial position is enough for
  importQueryPackage to deduce the scope.
  It now works for queries in GoFiles, TestGoFiles, or XTestGoFiles.
  (It no longer works for ad-hoc main packages like
  $GOROOT/src/net/http/triv.go)

  More complete: "referrers" computes the scope automatically by
  scanning the import graph of the entire workspace, using gorename's
  refactor/importgraph package.  This requires two passes at loading.

  Faster: simplified start-up logic avoids unnecessary package loading
  and SSA construction (a consequence of bad abstraction) in many
  cases.

  "callgraph": remove it.  Unlike all the other commands it isn't
  related to the current selection, and we have
  golang.org/x/tools/cmdcallgraph now.

Internals:

  Drop support for long-running clients (i.e., Pythia), since
  godoc -analysis supports all the same features except "pointsto",
  and precomputes all the results so latency is much lower.

  Get rid of various unhelpful abstractions introduced to support
  long-running clients.  Expand out the set-up logic for each
  subcommand.  This is simpler, easier to read, and gives us more
  control, at a small cost in duplication---the familiar story of
  abstractions.

  Discard PTA warnings.  We weren't showing them (nor should we).

  Split tests into separate directories (so that importgraph works).

68b5f7541d cmd/oracle: usability improvements to "describe", "referrers"
Emacs integration:
- eliminate oracle minor mode
- in go-mode, bind F5, F6 to "describe", "referrers".
  This reverts a previous policy decision but convenience matters too.
- don't insist on an analysis scope for modes that don't do PTA.
- don't hide the filename as "▶"; show the last 20 chars.
  (Especially useful for "referrers" mode.)
- output postprocessing: don't get stuck in a loop if the output
  is not as expected (e.g. when it includes a panic log).

referrers:
- show the matching lines (like grep does).
  We do the I/O in parallel.

0c09ff325a cmd/cover: preserve //go: comments
Cover deleted all comments because they can break the simple way that
counters are injected into the rewritten source. But //go: comments have
semantic value, and for instance go test -cover runtime fails during
compilation because of their absence from the annotated source.

We can keep the //go: comments because they are at the beginning of
the line and are not affected by our counter injection.

Fixes #10270.

After this CL, go test -cover runtime works.
A testing strategy that does not involve a golden file would be welcome
but I can't think of one.
