[X86] Make all instructions that operate on MMX types, but were added after the initial MMX support via one of the SSE features flags make them require the MMX feature as well.

Passing -mattr=-mmx needs to disable these instructions since the MMX register class won't have been set up. But we don't want -mattr=-mmx to disable SSE so we have to do it separately.
