    libstdc++: don't implicit-construct _Yielded_decvref [PR118022]

    This overload requires

      constructible_from<remove_cvref_t<yielded>,
                         const remove_reference_t<yielded>&>

    ... but then tries to construct remove_cvref_t<yielded> implicitly,
    which means it imposes an additional constraint not in the standard.

    libstdc++-v3/ChangeLog:
