    libstdc++: Fix std::array<T, 0>::data() to be a constant expression
[PR108258]

    When I refactored the __array_traits helper I broke this.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108258
            * include/std/array (__array_traits<T, 0>::operator T*()): Add
            constexpr.
            * testsuite/23_containers/array/element_access/constexpr_c++17.cc:
Check
            std::array<T, 0>::data().
