--- Comment #25 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think the regression is fixed - we perform alias versioning unnecessarily
but we are now entering the vectorized loop for a == b (in fact RTL opts
eventually elide the versioning check, so the resulting code is optimal).
This was fixed in GCC 10.
I've split out remaining missed optimization to PR109271.
