internal/imports: load test exports of package under test

x_tests can access exports from the test variant of the package under
test. Change loadExportsFromFiles to understand that mode, and use it
where appropriate.

I didn't want to come up with a cache key for for the test variant, so
for now we bypass the cache in these situations.

Fixes golang/go#29979.

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.
