  Log Message:
  -----------
  [TargetLowering] prepareUREMEqFold/prepareSREMEqFold - account for non legal shift types

Ensure we tell getShiftAmountTy that we're working with pre-legalized types to prevent cases where the (legalized) shift type can no longer handle the (non-legalized) type width.
