    libstdc++: Make join_view::_Iterator::_M_get_inner noexcept [PR121804]

    Since this helper (added in r16-3576-g7f7f1878eedd80) is used in the
    noexcept-spec of iter_move and iter_swap, it in turn needs an accurate
    noexcept-spec.

            PR libstdc++/121804

    libstdc++-v3/ChangeLog:

            * include/std/ranges (join_view::_Iterator::_M_get_inner):
            Mark noexcept.
            * testsuite/std/ranges/adaptors/join.cc (test16): New test.
