Allows preserving MachineMemOperands on intrinsics through selection. For reasons I don't understand, this is a static property of the pattern and the selector deliberately goes out of its way to drop if not present. Intrinsics already inherit from SDPatternOperator allowing them to be used directly in instruction patterns. SDPatternOperator has a list of SDNodeProperty, but you currently can't set them on the intrinsic. Without SDNPMemOperand, when the node is selected any memory operands are always dropped. Allowing setting this on the intrinsics avoids needing to introduce another equivalent target node just to have SDNPMemOperand set. llvm-svn: 321212
