[PATCH] [TSan][MIPS] Adding support for MIPS64

[Sagar Thakur]

Hi @samsonov

On X84_64, with the previous patch, standalone compilation was failing with -DCOMPILER_RT_INCLUDE_TESTS=ON because of a cmake error. This was happening because the funtion `get_target_flags_for_arch ()` in `add_tsan_unittest` macro was revieving incorrect arch value in its first argument.
I have added changes to enable unit tests for all architectures in lib/tsan/test/CMakeList.txt in this patch.

Does this change look good ?
