    libstdc++: Fix -Wsystem-headers warnings in tests
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/18_support/new_nothrow.cc: Add missing noexcept
            to operator delete replacements.
            * testsuite/20_util/any/cons/92156.cc: Disable
            -Winit-list-lifetime warnings from instantiating invalid
            specialization of manager function.
            * testsuite/20_util/any/modifiers/92156.cc: Likewise.
            * testsuite/20_util/default_delete/void_neg.cc: Prune additional
            diagnostics.
            * testsuite/20_util/headers/memory/synopsis.cc: Add missing
            noexcept.
            * testsuite/20_util/shared_ptr/cons/void_neg.cc: Prune
            additional diagnostic.
            * testsuite/20_util/unique_ptr/creation/for_overwrite.cc: Add
            missing noexcept to operator delete replacements.
            * testsuite/21_strings/basic_string/cons/char/103919.cc:
            Likewise.
            * testsuite/23_containers/map/modifiers/emplace/92300.cc:
            Likewise.
            * testsuite/23_containers/map/modifiers/insert/92300.cc:
            Likewise.
            * testsuite/24_iterators/headers/iterator/range_access_c++11.cc:
            Add missing noexcept to synopsis declarations.
            * testsuite/24_iterators/headers/iterator/range_access_c++14.cc:
            Likewise.
            * testsuite/24_iterators/headers/iterator/range_access_c++17.cc:
            Likewise.
