[X86] combineAnd() - per-element simplification - call SimplifyDemandedBits using mask demanded bits if SimplifyDemandedVectorElts fails

We already call SimplifyDemandedVectorElts using whether each vector mask element is zero/nonzero, this just extends this to also try SimplifyDemandedBits using the demanded bits mask generated from the nonzero elements.

This also requires an additional TargetLowering::SimplifyDemandedBits DemandedBits/DemandedElts wrapper.
