This change updates the language accepted through the arguments
to packages.Load to make it more consistent. There are now two layers.
A pattern containing an "=" is considered to be a special query, and the
part of the pattern up to the first "=" is considered the query type. All
other patterns are to be interpreted as the build system interprets it.
For now two special queries exist. file= has the behavior that contains:
did: finding packages containing the given file. The query type pattern=
is used to pass through a pattern to be interpreted by the build system.
pattern= is a type of escaping to allow passing through patterns that
contain an "=" to be interpreted by the underlying buildsystem. To allow
for new query types to be introduced, packages.Load will report an
error if the qury type is not understood. We expect name= to be added in
an upcoming change.

We plan to change goimports to use go/packages, which requires changing
its internal design. Having tests use the external interface makes those
changes easier. After this change almost all testing is through Process.
Broadly speaking, the changes are:
- Switch to subtests wherever possible. This involved making up many
names, which I hope are accurate.
- Convert tests that used findImport directly to use Process instead.
This often made them slightly larger but not unduly IMO.
- Replace simple tests with entries in the giant table at the top.
- Remove uses of custom goroots, which are troublesome for
go/packages' use of the go command. Almost none of them were actually
necessary. I left one in TestGoRootPrefixOfGoPath; I'm not sure how
to handle it yet.

This CL makes no functional changes, but may change performance

The typechecker's Sizes function is not currently set correctly.
The correct answer requires information known only to the build
system's query tool (go list, blaze query, etc), and we need to
add a mechanism for it to return this information.
In the meantime, we use this simple workaround: if the GOARCH
environment variable is set, we use that to determine sizes according
to the conventions of gc. Otherwise, we use the architecture for which
the application was compiled. Both could easily be incorrect, but this
is nonetheless progress.
This change should fix the tests of go/analysis/passes/shift,
which are currently broken for GOARCH=386 because the analysistest
driver uses go/packages, which ignores GOARCH.

The ctrlflow Analyzer builds a control-flow graph (see

It computes for each function whether it can never return, either
because the function is an intrinsic that stops the thread (e.g.
os.Exit), or because control never reaches a return statement, or
because the function inevitably calls another function that never
returns. For each such function it exports a noReturn fact.

- adds 'inspect', another Analyzer that builds an optimized AST
traversal table for use by nearly every other Analyzer.
- changes analysistest.Run to return the analysis result to enable
