Ian Cottrell 619897c5a2 go/packages/packagestest: add marker support
This adds a library that allows markers and actions inside comments in go source
files.
It then also adds an easy way to use that library for tests using packagestest.Expect
This is used to easily write code inspection and manipulation tests in a
language that is common to all tests.

Heschi Kreinick 00c5fa5868 go/packages: find mismatched top level packages in name=
Treat the top-level package of a module specially so that the VCS
working dir name doesn't have to match the package name. Generally we
take the position that directory names should match packages, but for
the top-level package that's a pretty strict requirement. Now we always
check the top-level directory, just in case.

Heschi Kreinick f60e5f99f0 go/packages/packagestest: use a module proxy
Instead of writing replace directives to link the test's modules
together, fill a GOPROXY dir and use `go mod download` to fill a real
GOCACHE with them. This makes the tests more realistic, since replace
directives will be somewhat unusual. It also gives the name= query
something to search.

Actually doing this in a way that's compatible with packagestest's
abstraction is a little tricky, since it wants to know where the files
will be. The actual files will be created by go mod download, so we have
to get Export to put them there to begin with, then move them out of the
way.

Since the GOPROXY zip format doesn't support symlinks, those will only
work in the primary module.

Heschi Kreinick e74f1bd585 imports: port tests to packagestest
I tried to introduce new modules where it made sense. I deleted the
weird goroot test because I removed the optimization it was testing in
an earlier CL.

Ian Cottrell 06f26fdaaa go/packages/packagestest: Testing with multiple drivers
This extracts some of the test code from packages, and adds the ability to run
the same test with multiple drivers.
This should generally be useful for all tools that run on top of go/packages as
well when writing tests for them.
