I don't want to unnecessarily expand your scope, but while you're
doing this, it might make sense to keep in mind the new Larrabee
instructions as well. They operate on 512-bit registers, and there's a
(slightly indirect) reference available here:
I'm not suggesting adding these now, just that they might be
interesting to keep in mind while you're doing this work.
