[X86] SimplifyDemandedVectorEltsForTargetNode - simplify PMADDWD for known zero elements
Noticed while investigating the regressions in D110995 - if the RHS element is already zero, then we don't need the corresponding LHS element.
Technically we could also recheck RHS once we have LHS's known zeros, but I haven't seen any missed opportunities from that yet.
