It can. The vectorizer will just emit it separately, shift unconditionally and conditional move from the result of that and some other value (0 or some value). And then the combiner can combine them together, like it handles many other cases. Except that right now you only handle it in define_expand. So, guess we need a pattern that will handle it later on too.
