    libstdc++: Remove noexcept from match_results comparisons (PR 94627)

    These functions can't be noexcept because the iterators stored in the
    sub_match objects can throw on any operation.

    libstdc++-v3/ChangeLog:

            PR libstdc++/94627
            * include/bits/regex.h (operator==, operator!=): Remove noexcept
            equality comparisons for match_results.
            * testsuite/28_regex/match_results/94627.cc: New test.
