    libstdc++: Inline all basic_string::compare overloads [PR59048]

    Defining the compare member functions inline allows calls to
    traits_type::length and std::min to be inlined, taking advantage of
    constant expression arguments. When not inline, the compiler prefers to
    use the explicit instantiation definitions in libstdc++.so and can't
    take advantage of constant arguments.

    libstdc++-v3/ChangeLog:

            definitions.
            * include/bits/cow_string.h (compare): Define inline.
            * testsuite/21_strings/basic_string/operations/compare/char/3.cc:
