    aarch64: Use a global map to detect duplicated overloads [PR112989]

    As explained in the covering note to the previous patch,
    the fact that aarch64-sve-* is now used for multiple header
    files means that function_builder::add_overloaded_function
    now needs to use a global map to detect duplicated overload
    functions, instead of the member variable that it used previously.

            new global.
            (add_overloaded_function): Update accordingly, using get_identifier
            to get a GGC-friendly record of the name.
