Subject: [PATCH] Convert flag_finite_math_only uses in frange to HONOR_*.
As mentioned earlier, we should be using HONOR_* on types rather than
flag_finite_math_only.
gcc/ChangeLog:
* value-range.cc (frange::set): Use HONOR_*.
(frange::verify_range): Same.
* value-range.h (frange_val_min): Same.
(frange_val_max): Same.
