--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
OK, so I guess std::vector<int>::_M_move_assign showed it in GCC 8 but then
with GCC 9 making 'this' restrict improved things here. But _M_move_assing
has the stores/loads interleaved so the simple pattern-matching wouldn't work
since we'd have to look through non-aliasing VDEFs.
