    libstdc++: Do not apply localized formatting to NaN and inf [PR114863]

    We don't want to add grouping to strings like "-inf", and there is no
    radix character to replace either.

    libstdc++-v3/ChangeLog:

            PR libstdc++/114863
            * include/std/format (__formatter_fp::format): Only use
            _M_localized for finite values.
            * testsuite/std/format/functions/format.cc: Check localized
            formatting of NaN and initiny.
