[TargetLowering] Add root node back to work list after successful SimplifyDemandedBits/SimplifyDemandedVectorElts

Similar to what already happens in the DAGCombiner wrappers, this patch adds the root nodes back onto the worklist if the DCI wrappers' SimplifyDemandedBits/SimplifyDemandedVectorElts were successful.
