This patch (on top of https://reviews.llvm.org/D40899 and https://reviews.llvm.org/D40900) primarily serves to document what I did to test the Solaris sanitizer support
on SPARC.

While initial results inside the gcc tree have been almost as good as the Solaris/x86
results, it's currently useless with clang since most tests fail due a llvm sparc backend
limitation:

fatal error: error in backend: Function "_ZN7testing8internal16BoolFromGTestEnvEPKcb": over-aligned dynamic alloca not supported.

Nonetheless, here's what the patch does:

- Add 32 and 64-bit sparc to compiler-rt

- lib/builtins/fp_lib.h needed to check if the __int128_t and __uint128_t types exist (which they don't on sparc)
