They're the current Cog definitions in sqAtomicOps.h & sqMemoryFence.h
corrected for x86_64.  They use the __sync_... gcc builtins if available,
falling back on gcc extended asm if not, i.e. for the win32 VM compiled
using gcc 3.x.  The __sync_ version are available in gcc as of 4.1, and are
in clang.  On iPhone they use the relevant SDK builtin,
e.g. OSAtomicCompareAndSwap32 or OSAtomicCompareAndSwap64.

Please review?
