atomic: prefer GCC __sync_*() builtins over inline asm
Use GCC __sync_*() builtins when compiler claims to be GCC (GCC itself,
Clang...)
It can be disabled explicitly by using XS_DISABLE_GCC_SYNC_BUILTINS
define. Just for any case.
* src/atomic_counter.hpp [__GNUC__ && !XS_DISABLE_GCC_SYNC_BUILTINS]:
(atomic_counter_t::add):
(atomic_counter_t::sub):
* src/atomic_ptr.hpp [__GNUC__ && !XS_DISABLE_GCC_SYNC_BUILTINS]:
(atomic_ptr_t::xchg):
(atomic_ptr_t::cas):
Prefer GCC __sync_*() builtins over inline asm.
