    c++: Fix ICE with using and virtual function. [PR95719]

    conversion_path points to the base where we found the using-declaration,
not
    where the function is actually a member; look up the actual base.  And =
then
    maybe look back to the derived class if the base is primary.

    gcc/cp/ChangeLog:

            * call.c (build_over_call): Look up the overrider in base_binfo.
            * class.c (lookup_vfn_in_binfo): Look through BINFO_PRIMARY_P.
