If there was never a DXILResourceWrapperPass initialized then preserving it is a no-op. This is needed so that *if* the DXILResourceWrapperPass ran before this pass we don't need to recalculate it again *after* this pass. If we don't do this then we need to run resource analysis twice in our pipeline.
