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.)

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are no longer valid -scope arguments, which broke most of the tests.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.

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).

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.
