Yes, I noticed this. For scalar code we can handle the mess caused by
if-conversion in RTL optimization, for vectorized code we cannot.
I have a patch that fixes it for -O3 at least - for -Ofast we run foul
of if-conversion changing the conditions from < 0.0 to >= 0.0 on the
else branch.
I'll think about the best way of dealing with that.
