--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ok, so this relied on tree loop if-conversion. Not sure if it really should
though (tree loop if-conversion has no cost model). I'd rather have RTL
if-conversion do the if-conversion if profitable.
Otherwise the regression can be easily fixed by adding -ftree-loop-if-convert
(though I'd recommend against this).
