	I don't think SSE2 is likely to give us significant wins - most real
perf. problems are algorithmic. In the area where it might - heavy duty
compilation, then assuming you have a sensible OpenCL compiler that will
detect & use whatever 31337 CPU features it can for bulk computation and
yet work on older machines.

	At least that's the theory; so I guess we'd want to back-down to SSE1
etc. (Michael S. has a nice patch)
