9c7ccd869c refactor/rename: emacs: kill go-rename buffer correctly
Match gofmt's behaviour of closing the status buffer. Don't display the
buffer in case of success as we were going to hide it instantly again,
anyway. Also, instead of using delete-window, use
gofmt--kill-error-buffer. gofmt--kill-error-buffer uses quit-window if
there's a window for the buffer, kill-buffer otherwise.

quit-window only deletes the window if it was created explicitly for the
status buffer and if it is still displaying it. This way, we won't close
windows that the user created or repurposed himself.

Additionally, this change ensures that we don't leave a *go-rename*
buffer lying around when gorename succeeded.

Fixes golang/go#10972.

500e956000 oracle: attempt to deduce callees statically before building SSA
When querying for callees against a static call, the entire SSA
form for the program was built. Since we can tell if a callee is
statically dispatched after typechecking, try to do that before
building the SSA form.

This cuts 3.5 seconds off queries against static calls.

3f8aef80c8 go/ast/astutil: set Pos for import name
Failing to set this when adding a named import
to an existing block at the 0th position
caused the Lparen position to be set to zero.
As a result, the specs were printed as if
they were a single spec, not a group.
This made it appear as if imports had
been swallowed.

See CL 8663 for more context
and the original bug report.

CL 2050 fixed most similar cases
but missed this one.

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.

+ Tests.

7534f4943d x/tools/cmd/stress: add utility for stress testing
The stress utility is intended for catching of episodic failures.
It runs a given process in parallel in a loop and collects any failures.
Usage:
 	$ stress ./fmt.test -test.run=TestSometing -test.cpu=10
You can also specify a number of parallel processes with -p flag;
instruct the utility to not kill hanged processes for gdb attach;
or specify the failure output you are looking for (if you want to
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.

Remove all dependencies from non-test code in go/ssa to go/loader,
except the deprecated Create function which will be eliminated in
favor of ssautil.CreateProgram in a mechnanical followup.

Add Examples of two main use cases of SSA construction:
loading a complete program from source; and
building a single package, loading its dependencies from import data.

Add tests to ssautil of the two load functions.
Suggestions welcome for better names.

Planned follow-ups:
- replace all references to ssa.Create with ssautil.CreateProgram and eliminate it.
- eliminate support in go/loader for the ImportBinary flag, and the
  PackageCreated hook which is no longer needed since clients can
  create the package themselves (see Example).

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.

dce4131cda oracle: referrers: also scan *_test.go files for references.
Added test case.  This required making the result sort order
deterministic when the results are spread across several packages.

Also: implements: print type names relative to query package.
Updated tests.

a27f5b3448 oracle: factor part of the initial setup for PTA queries
The check for len(argv)==0 now only applies to these modes.

Also, more consistent variable naming.
