    libstdc++: Ensure that ranges::destroy destroys in constexpr [PR121024]

    The new test is currently marked as XFAIL because PR c++/102284 means
    that GCC doesn't notice that the lifetimes have ended.

    libstdc++-v3/ChangeLog:

            PR libstdc++/121024
            * include/bits/ranges_uninitialized.h (ranges::destroy): Do not
            optimize away trivial destructors during constant evaluation.
            (ranges::destroy_n): Likewise.
            * testsuite/20_util/specialized_algorithms/destroy/121024.cc:
            New test.
