We're probably at the point where we should just have a generic descriptor that
can give you up to, say 3, registers to use for a descriptor. That way we don't
always need to make these descriptors platform specific. You're likely not
choosing based on a careful profile ;) (Different CL, just an observation)

Good idea!
