Talking to John and Doug, we concluded that these functions from stdatomic really do belong here in compiler-rt rather than in libc, since the compiler owns stdatomic.h and these need to refer to clang-specific builtins. Nonetheless, I've only added these on darwin for now - other platforms should probably do the same unless their libc does implement these functions. llvm-svn: 236805
