This test can't pass on MIPS64 due to the lack of versioned interceptors
for asan and company. The interceptors bind to the earlier version of
sem_init rather than the latest version. For MIPS64el this causes an
accidental pass while MIPS64 big endian fails due reading back a
different 32bit word to what sem_init wrote when the test is corrected
to use 64bit atomics.

Summary:
Part of https://github.com/google/sanitizers/issues/637
Standalone ubsan needs signal and sigaction handlers and interceptors.
Plugin mode should rely on parent tool.

The commit did not fix the failing test and instead exposed an inconsistency
between lsan and (t|m|a)san. I'm reverting the patch as it causes more failures
and the original patch had a '||' instead of '&&', which meant that an N32 build
of test would have be incorrect w.r.t. __HAVE_64B_ATOMICS for glibc.
This reverts commit r313248.
llvm-svn: 313291
glibc changed the implementation of semaphores for glibc 2.21 requiring
some target specific changes for this compiler-rt test. Modify the test
to cope with MIPS64 and do some future/correctness work by tying the
define for MIPS64 to exactly the define of __HAVE_64B_ATOMICS in glibc.

Summary:
Failing tests just marked as UNSUPPORTED or XFAIL.
Some of them can be easily supported, but I'll do this in separate patches.

Summary:
Augment SanitizerCoverage to insert maximum stack depth tracing for
use by libFuzzer. The new instrumentation is enabled by the flag
-fsanitize-coverage=stack-depth and is compatible with the existing
trace-pc-guard coverage. The user must also declare the following
global variable in their code:
thread_local uintptr_t __sancov_lowest_stack
