    libstdc++: Revert changes to std::unique_ptr<T[]>::operator[] [PR 101271]

    This reverts the changes in r12-1778 which added a noexcept-specifier to
    std::unique_ptr<T[]>::operator[], and the changes in r12-1844 which
    tried to make it work with incomplete types (for PR 101236).

    The noexcept-specifier is not required by the standard, and is causing
    regressions, so just remove it.
