We plan to reuse goimports' directory walking logic in the
implementation of go/packages. To prepare for that, refactor it to have
fewer global variables and a simpler interface.
This CL makes no functional changes, but may change performance
slightly. It always scans both $GOPATH and $GOROOT, and does so
serially. I expect that fastwalk's internal parallelism is enough to
keep the disk busy, and I don't think it's worth optimizing for people
hacking on Go itself.

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.

This checker needed some reworking because whereas vet sees

However, that means the checker must effectively undo some of the

cgo.

- The old cmd/vet driver would run this check on all the files in

The ctrlflow Analyzer builds a control-flow graph (see
golang.org/x/tools/go/cfg) for each named and unnamed function in the
package.
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.
This change also:
- 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
further testing.
(This required changing it to analyze one package at a time,
which is no less efficient, and is the typical case.)
