    [PR106967] Set known NANs to undefined for flag_finite_math_only.

    Explicit NANs in the IL can be treated as undefined for
    flag_finite_math_only.  This causes all the right things to happen wrt
    threading, folding, etc.  It also saves us special casing throughout.

            * value-range.cc (frange::set): Set known NANs to undefined for
            flag_finite_math_only.
