The patch adds better target_triple and target_arch defaults for lit tests,
which allows us to XFAIL tests based on architecture.
Was:
target_triple = LLVM_DEFAULT_TARGET_TRIPLE
target_arch = HOST_ARCH
Now:
target_triple = COMPILER_RT_TEST_TARGET_TRIPLE
, otherwise LLVM_DEFAULT_TARGET_TRIPLE
target_arch = first item in COMPILER_RT_TEST_TARGET_TRIPLE

TSan can produce false positives in code that uses C++11 threading,
as it doesn't see synchronization inside standard library. See
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-February/035408.html
for an example of such case.
We may build custom TSan-instrumented version libcxx to fight with that.
This change adds build rules for libcxx_tsan and integrates it into
testing infrastructure.
