Correct atomic libcall support for __atomic_*_fetch builtins.
In r244063, I had caused these builtins to call the same-named library
functions, __atomic_*_fetch_SIZE. However, this was incorrect: while
those functions are in fact supported by GCC's libatomic, they're not
documented by the spec (and gcc doesn't ever call them).
Instead, you're /supposed/ to call the __atomic_fetch_* builtins and
then redo the operation inline to return the final value.
