FWIW, I think the reason I mentioned for skimping on this originally
was that we don't e.g. prevent if-conversion of:

void
foo (int *c, float *f)
{
  for (int i = 0; i < 16; ++i)
    f[i] = c[i] ? __builtin_sqrtf (f[i]) : f[i];
}

for -O2 -ftree-vectorize -fno-math-errno.  So it seemed like things
weren't very consistent.
