Updated patch
Well, here's an update also for AVX512F.
I can confirm the patch gives the same performance as the AVX
version on a machine that supports AVX. Untested on AVX512, because
I don't have a machine for that.
Adding AVX2 would be fairly trivial.
I'm not sure that yanking out the info into the new cpuinfo.h header
file is the way to go, but I am not sure of a better way to do it.
Other comments?
