I haven't looked through all the SSE instructions, so there might be
something useful. However, SMC32 already makes use of the 64-bit MMX
registers (useful for counts) and I think you're not worse off using
those compared to the newer 64-bit instructions unless you're trying to
do floating point at the same time (MMX and FPU registers being shared).
