Ok, so the issue was fixed in g:74166aabeb7f22990476b1169bba031b8323ee92, which
is about a preferred vector types.
So with the following patch:

I tracked that it was fixed with g:04b99da898a9817e72fedb4063589648b7961ac5,
which is a vectorizer related revision.
Thus it's likely dup of PR97236.
Can we backport the fixed into 8 and 9 branch?
