--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think both passes are valid placed to improve this. The vector constructor
could be from the original source as well.
Note vector lowering already tries to compute a "compute mode", but not in
all lowering paths IIRC and possibly not aware of VLA vectors or "LMUL".
