Avoid extra nop_full in stack_pop_acquire if atomic intrinsics used (x86)
* src/atomic_ops/generalize.h [AO_HAVE_double_compare_and_swap_acquire]
(AO_compare_double_and_swap_double_acquire): Implement (by redirecting
to AO_double_compare_and_swap_acquire).
* src/atomic_ops/generalize.h [AO_HAVE_double_compare_and_swap_release]
(AO_compare_double_and_swap_double_release): Implement (by redirecting
to AO_double_compare_and_swap_release).
