Don't consider !Unpin references as noalias
Such structures may contain self-references, in which case the same location may be accessible through a pointer that is not based-on the noalias pointer. This is still grey area as far as language semantics are concerned, but checking for !Unpin as an indicator for self-referential sturctures seems like a good approach for the meantime.
