ShallowOOMDeepCrash.cpp may hit libFuzzer's RSS limit before the SIGUSR2
is delivered, causing the test to be flaky when bots are under load.
SleepOneSecondTest.cpp will keep running until the signal is delivered.

pkill reads the process name as a pattern, not a raw name. This means
that if the process name contains + or other regex characters, pkill
fails.

The tests fork.text, fork.sigusr.test and fork-ubsan.test intermittently
fail on the aarch64 buildbots. Input gathered from the fork.sigusr.test
implies that when the builder is under load the timeout value is not
sufficient. The fork-ubsan.test doesn't have a timeout and I think is not
always finding the error after 10000 runs so I've marked it as unsupported
for now.

The fork-siguser.test and fork.test intermittently fail on the AArch64
buildbot. Unfortunately these failures are not reproducible on a similar
machine and seem to fail when the machines are under load. Before
suggesting the tests be marked unsupported for AArch64 we'd like to see
if we can get some more information about the failures to see if it helps
us reproduce. This patch adds --dump-input-on-failure to the FileCheck
commands to see if we can get some more information about the failures.

Summary:
Port libFuzzer's fork mode to Windows.
Implement Windows versions of MkDir, RmDir, and IterateDirRecursive to do this.
Don't print error messages under new normal uses of FileSize (on a non-existent file).
Implement portable way of piping output to /dev/null.
Fix test for Windows and comment fork-sigusr.test on why it won't be ported to Win.
