Siva Chandra Reddy f6d74b29d6 [libc][NFC] Disable a loader test as ld.gold fails to link.

Siva Chandra Reddy db936e0e91 [libc][NFC] Add library of floating point test matchers. 
This eliminates UnitTest's dependency on FPUtil and hence prevents
non-math tests from depending indirectly on FPUtil. The patch
essentially moves some of the existing pieces into a library of its own.

Along the way, renamed add_math_unittest to add_fp_unittest.

Siva Chandra Reddy 5d59385ba6 [libc] Setup TLS in x86_64 loader. 
The new code added is still very x86_64 specific. AArch64 support will
be added very soon and refactoring of the loader code will be done as
part of the patches adding it.

Siva Chandra Reddy a32af8252f [libc] Add a tool called WrapperGen. 
This tool will be used to generate C wrappers for the C++ LLVM libc
implementations. This change does not hook this tool up to anything yet.
However, it can be useful for cases where one does not want to run the
objcopy step (to insert the C symbol in the object file) but can make use
of LTO to eliminate the cost of the additional wrapper call. This can be
relevant for certain downstream platforms. If this tool can benefit other
libc platforms in general, then it can be integrated into the build system
with options to use or not use the wrappers. An example of such a
platform is CUDA.
