This patch implements -fsanitize=float-divide-by-zero option that can
be used to detect division by zero even when using floating types.
Most of the code in ubsan_instrument_division was ready for this

Yes :-)
I'm testing the attached patch now. It compiles slightly faster
(-ftime-report shows, as expected, that less time is spent in template
instantiation).
