--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
On GIMPLE this could be pattern-matched to a VEC_PERM_EXPR <> which is
how to represent blends. Of course matching this on RTL is possible as well.
The difficulty is of course the mismatch in element sizes where the
mask appears to be byte granular while the data to be blended is double-words.
