Craig Topper 404ccdcfc2 [InstCombine][X86] Add DemandedElts support for 512-bit PMULDQ/PMULUDQ instructions 
PMULDQ/PMULUDQ vXi64 instructions only use the even numbered v2Xi32 input elements which SimplifyDemandedVectorElts should try and use.

This builds on r290554 which added supported for 128 and 256-bit.
