    libstdc++: Another merge from fast_float upstream [PR107468]

    Upstream fast_float came up with a cheaper test for
    fegetround () =3D=3D FE_TONEAREST using one float addition, one subtrac=
tion
    and one comparison.  If we know we are rounding to nearest, we can use
    fast path in more cases as before.
    The following patch merges those changes into libstdc++.
