If we have to build a test package, and if the full set of packages
being tested imports the regular package somewhere, then make building
the test package depend on building the regular package. That way if
the regular package fails to build we only report the error once.

this to (partially) port CL 363436, excluding issue49005.go, which does
not exist in go/types (it was added in a previous CL related to compiler
error messages, that was not ported). I've also included the bugfix from

In subsequent CLs I'll catch up with error handling locations in types2

This makes two changes: (1) mutator.mutate now only applies a single
mutation to the input, and (2) in workerServer.fuzz if, after five
mutations are applied to the input, no new coverage is found the input
is reset to its initial state. This process is repeated until new
coverage is found, or the fuzz call times out.
This results in finding new coverage expanding inputs which have less
divergence from the initial input they were mutated from, which makes
traversing certain types of call graphs significantly more efficient.

exec_test.go's init function uses os.NewFile(fd) + f.Stat as a portable
mechanism to determine if an FD is in use.
Unfortunately, the current use is racy: if an unused FD becomes used
between NewFile and f.Close, then we will unintentionally close an FD we
do not use.
We cannot simply drop Close, as the finalizer will close the FD. We
could hold all of the os.Files in a global for the lifetime of the
process, but the need for such a hack is indicative of the larger
problem: we should not create an os.File for an FD that we do not own.
Instead, the new fdtest.Exists provides a helper that performs the
equivalent of fstat(2) on each OS to determine if the FD is valid,
without using os.File.
We also reuse this helper on a variety of other tests that look at open
FDs.
