    libstdc++: Add <bits/binders.h> to freestanding headers [PR125112]
    
    The <ranges> header was added to the freestanding headers in
    r16-3575-g1a41e52d7ecb58 but bits/binders.h that it depends on was not
    moved, making <ranges> unusable with --disable-libstdcxx-hosted.

            bits_freestanding.
