Daniel Martí c3e1567727 go/packages: make tests pass with custom GOCACHE
This commit was merged earlier with some failing trybots, so it was
reverted. This is a re-submission.

Before this change, a test would fail:

	$ GOCACHE=$HOME/go/cache go test
	--- FAIL: TestLoadImportsGraph (0.36s)
	    --- FAIL: TestLoadImportsGraph/GOPATH (0.19s)
		packages_test.go:191: golang.org/fake/subdir/d.test.Srcs = [4302876da86a8aae0c1669924daa223cafca60ef49ccaa060ae37e778d18f218-d], want [0.go]
	    --- FAIL: TestLoadImportsGraph/Modules (0.17s)
		packages_test.go:191: golang.org/fake/subdir/d.test.Srcs = [4302876da86a8aae0c1669924daa223cafca60ef49ccaa060ae37e778d18f218-d], want [0.go]
	FAIL

This is because it assumed that the user hadn't set their own GOCACHE,
and thus that all source files in the cache would be under the default
"go-build" cache directory.

We could fix this via os.Getenv("GOCACHE"), but a simpler mechanism is
to see if the source file has an extension. Source files don't have an
extension in GOCACHE, so that's much simpler to detect.

After this change:

	$ GOCACHE=$HOME/go/cache go test
	PASS

golist_fallback.go also had a bit of code to add "/go-build/" to the
added testmain.go path, to trick the tests on Go 1.10 to think the file
was in GOCACHE. Update that code too, to now not add ".go" to the path
instead.

While at it, gofmt.

Fixes golang/go#29445.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your subdir):" in the subject line, so it is easy to find.
