Workaround a bug in double-wide CAS intrinsic of Apple clang-600/x64
The bug causes test_stack failure.
* src/atomic_ops/sysdeps/gcc/x86.h
[AO_GCC_ATOMIC_TEST_AND_SET && __APPLE_CC__ && __x86_64__]: Fall-back
to asm-based implementation of double-wide CAS
(AO_compare_double_and_swap_double_full); add comment explaining the
reason.
* src/atomic_ops/sysdeps/gcc/x86.h
[__GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 && AO_GCC_ATOMIC_TEST_AND_SET
&& __APPLE_CC__] (AO_SKIPATOMIC_double_compare_and_swap_ANY): Define.
