Do not define AO_GCC_FORCE_HAVE_CAS for Clang 3.8+ (Aarch64)
(Cherry-pick commits 83fca68, baa9851 from 'master' branch.)

Clang now defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_n macros (so,
the workaround is not needed anymore).

* src/atomic_ops/sysdeps/gcc/aarch64.h (AO_GCC_FORCE_HAVE_CAS):
Do not define if AO_CLANG_PREREQ(3, 8) (unless __APPLE_CC__).
