[SelectionDAG] Add demanded elts variants to isConstOrConstSplat helpers. NFCI.
These helpers extend the existing isConstOrConstSplat helper checks to support DemandedElts masks as well.
We already had a local version of this in SelectionDAG that computeKnownBits/ComputeNumSignBits made use of, but this adds the functionality directly to the BuildVectorSDNode node and extends isConstOrConstSplat etc. to use that.
This will allow us to reuse the functionality in SimplifyDemandedVectorElts/SimplifyDemandedBits.
