2010-02-18  Ivan Maidanski <ivmai@mail.ru>

* src/atomic_ops/sysdeps/gcc/x86_64.h (AO_nop_full): Don't check
for AO_USE_PENTIUM4_INSTRS (since "mfence" (SSE2) is supported on
all x86_64/amd64 chips); remove the comment.
* src/atomic_ops/sysdeps/msftc/x86_64.h (AO_nop_full): Ditto.
* src/atomic_ops/sysdeps/msftc/x86_64.h (AO_nop_full): Define only
if AO_ASM_X64_AVAILABLE.
* src/atomic_ops/sysdeps/gcc/x86_64.h (AO_compare_and_swap_full):
Use built-in __sync_bool_compare_and_swap() if GCC v4.2+.
