Do not define AO_GCC_FORCE_HAVE_CAS for Clang 3.8+ (Aarch64)
(fix commit 83fca68)

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,
AO_GCC_HAVE_double_SYNC_CAS): Do not define if AO_CLANG_PREREQ(3, 8)
(unless __APPLE_CC__).
