--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
extending simplify_vector_constructor to support loads would indeed be nice,
the first check should be to key on the same VUSE for all loads and only then
do more expensive checking, possibly using dataref analysis and sorting
according to what the vectorizer dataref group analysis does.
