When using faketime, only run the scavenger for one loop.
It tries to run for 1 ms, but with faketime that calculation fails.
Prohibit write barriers in the faketime write function, in case
the GC wants to print something (e.g., with GODEBUG=gctrace=1).

Introduce a new constant compilerErrorMessages, which is set to false
for now, so that we can port types2 error handling more precisely. Use
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
CL 364034, so that go/types is not broken at this commit.
In subsequent CLs I'll catch up with error handling locations in types2
that use compiler error messages.

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.

We can improve the situation by looking for pointer equality with the

the compiler, go/types, and go/internal/gcimporter. CL 364194 makes the
