Do not set NAN flags for VARYING ranges when !HONOR_NANS.
Since NANs can't appear in ranges for !HONOR_NANS, there's no reason
to set them in a VARYING range.
gcc/ChangeLog:
* value-range.h (frange::set_varying): Do not set NAN flags for
!HONOR_NANS.
* value-range.cc (frange::normalize_kind): Adjust for no NAN when
!HONOR_NANS.
(frange::verify_range): Same.
* range-op-float.cc (maybe_isnan): Remove flag_finite_math_only check.
