With the advent of the __llvm_gcov_flush function, we need to be able to merge
counts into the .gcda files in an intelligent manner. This involves reading the
file if it exists, adding the counts together, and then writing the results.

[TSan] Add initial support for buidling ThreadSanitizer runtime library with CMake (currently the only supported platfrom is 64-bit Linux). This patch makes 'clang++ -fthread-sanitizer' work for both clang in the build tree and installed clang

[Sanitizer] don't use -Werror as default compile flag for sanitizer runtimes - people may use too many distinct/old host compilers

In code review, it looked like these warnings do not actually fire with
modern Clang or GCC. However, the pragma is flat out rejected by GCC in
many configurations (-Werror) so it ended up causing more problems than
it fixed.

Daniel agreed with reverting this, but I think didn't have time to get
to it.
