libstdc++-v3/ChangeLog:

        PR libstdc++/102270
        * include/std/tuple (_Head_base, _Tuple_impl): Add
        _GLIBCXX20_CONSTEXPR to allocator-extended constructors.
        (tuple<>::swap(tuple&)): Add _GLIBCXX20_CONSTEXPR.
        * testsuite/20_util/tuple/cons/102270.C: New test.

Oops, this test has a .C extension, and so doesn't actually run (and
if I rename it to 102270.cc it fails).

Fix incoming ...
