--- Comment #1 from Eli Friedman <efriedma at quicinc.com> ---
Scalable autovec is supposed to be forced off, for now, because it isn't
finished.  This works correctly on the main branch.  If you want to try
experiment, you can try "-mllvm -scalable-vectorization=on".

Not sure why this isn't working correctly on 12.0... but 12.0.1 isn't taking
patches at this point, and there aren't any other planned 12.0 releases, so we
can't really backport a fix.
