Summary:
Lsan was using PTHREAD_CREATE_JOINABLE/PTHREAD_CREATE_DETACHED
as truthy values, which works on Linux, where the values are 0 and 1,
but this fails on OS X, where the values are 1 and 2.
Set PTHREAD_CREATE_DETACHED to the correct value for a given system.

I didn't pay enough attention to the patch I reverted, now I'm going to
hit it with a bigger hammer until we can understand what the problems
are.

This reverts commit r299957. It broke the Thumb bots. We need to make
sure why and maybe stop it from being tested on Thumb environments. But
for now, let's get the bots green.

Summary:
Not repeating screamy failure paths makes the 300+ line function a bit shorter.
There's no need to overload the variable name "Buffer" if it only works on the
thread local buffer. Fix some comments while there.
I plan to move the rewinding logic into a separate function too, but in this
diff it would be too much of a mess to comprehend. This is trivially NFC.

This patch applies a work-around to the XRay FDR tests when TSC emulation is
needed because the processor frequency cannot be determined.

llvm-svn: 299979
Summary:
The routines for thread destruction in the thread registry require
the lsan thread index, which is stored in pthread tls on OS X.
This means that we need to make sure that the lsan tls isn't destroyed
until after the thread registry tls. This change ensures that we
don't delete the lsan tls until we've finished destroying the thread
in the registry, ensuring that the destructor for the lsan tls runs
after the destructor for the thread registry tls.
This patch also adds a check to ensure that the thread ID is valid before
returning it in GetThreadID(), to ensure that the above behavior
is working correctly.

Previously in r297800, a work-around was created to use TSC emulation on x86_64 when RDTSCP was not available on the host. A similar change was needed in the file xray_fdr_logging.cc which this patch ports over to that file.
Eventually the code should be refactored as there will be 3 locations with the same code, but that can be done as a separate step. This patch is just to keep the test from failing on my machine due to an illegal instruction since RDTSCP is not available on my x86_64 linux VM.

Summary:
We can move this functionality into LLVM's tools instead, as it no
longer is strictly required for the compiler-rt testing infrastructure.
It also is blocking the successful bootstrapping of the clang compiler
due to a missing virtual destructor in one of the flag parsing library.
Since this binary isn't critical for the XRay runtime testing effort
anymore (yet), we remove it in the meantime with the hope of moving the
functionality in LLVM proper instead.
