This checker needed some reworking because whereas vet sees
unprocessed cgo source files (with partial type information), the
analysis API sees cgo-processed files with complete type information.
However, that means the checker must effectively undo some of the
transformations done by cgo, making it more fragile during changes to
cgo.

- The old cmd/vet driver would run this check on all the files in
a directory whereas new drivers will run it only on the files
selected for a particular configuration, so some of the checks
(those in checkArguments) will never fire. But this is not a regression
relative to 'go vet', because it too presents cmd/vet with only the

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.)
