go: don't crash if __atomic_fetch_add functions are used

Browse source 
The Go frontend only generates __atomic_add_fetch, but in some cases
thost calls become __atomic_fetch_add.

Patch originally by Marc Poulhiès.

	PR target/107581
	* go-gcc.cc (Gcc_backend::Gcc_backend): Define
	__atomic_fetch_add_{4,8}.
