Please attach your testcases to the bug report. godbolt links are nice
complements, but not considered sufficient here.

We don't lower the comparison or the blend in GIMPLE (yet). I think Hongtao Liu
is doing blends right now. I don't know if there would be issues for
comparisons (with -ftrapping-math for instance?).

If you write (x<y)?x:y with everything of type __m128, we do generated minps.
