    libstdc++: Adjust <format> for Clang compatibility [PR107712]

    Clang doesn't define __builtin_toupper, so use std::toupper.

    Also add some (not actually required since C++20) typename keywords to
    help Clang versions up to and including 15.

    libstdc++-v3/ChangeLog:

            PR libstdc++/107712
            * include/std/format (__format::__formatter_int::format): Use
            std::toupper when __builtin_toupper isn't available.
            (basic_format_arg::handle): Add 'typename'.
            * include/std/complex (complex<T>): Add 'typename'.
