compiler: intrinsify runtime/internal/atomic functions
Currently runtime/internal/atomic functions are implemented in C
using C compiler intrinsics. This CL lets the Go frontend
recognize these functions and turn them into intrinsics directly.
Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/176918
* go-gcc.cc (Gcc_backend::Gcc_backend): Define atomic builtins.
