[PATCH] D53801: [libc++abi] Provide __cxa_thread_atexit on Fuchsia

I don't know what's affected by the presence of that declaration.  Certainly it should be defined.
AFAICT this has nothing to do with solving the problem of the symbol not existing in the library.
That needs CMakeLists.txt:34 changed so it compiles cxa_thread_atexit.cpp for Fuchsia.
We also need to make sure that the cmake check for presence of __cxa_thread_atexit_impl in libc is passing correctly.
