[InstCombine][MMX] Extend SimplifyDemandedUseBits MOVMSK support to MMX 

Add the MMX implementation to the SimplifyDemandedUseBits SSE/AVX MOVMSK support added in D19614

Requires a minor tweak as llvm.x86.mmx.pmovmskb takes a x86_mmx argument - so we have to be explicit about the implied v8i8 vector type.
