    libstdc++: Ensure std::to_chars overloads all declared in <format>
[PR107720]

    For powerpc64le we need to be able to format both of __ieee128 and
    __ibm128, so we need the std::to_chars overloads for both types to be
    visible at once. The __ieee128 overloads are always visible in C++23
    mode, because they're used to implement the _Float128 overloads. The
    __ibm128 overloads are only visible when long double is __ibm128.

    libstdc++-v3/ChangeLog:

            PR libstdc++/107720
            * include/std/format [_GLIBCXX_LONG_DOUBLE_ALT128_COMPAT]:
            Declare overloads of std::to_chars for the alternative long
            double type.=
