Use __sync_add_and_fetch and __sync_sub_and_fetch when they are available These functions may be available as inlines or as libgcc functions. In the former case, a __GCC_HAVE_SYNC_COMPARE_AND_SWAP_n macro is defined. But we still want to use these functions in the latter case, when we don't have our own implementation.
