    Fix PR c++/109958: ICE taking the address of bound static member function
brought into derived class by using-declaration

    We currently ICE upon the following because we don't properly handle the
    overload created for B::f through the using statement.

    === cut here ===
    struct B { static int f(); };
    struct D : B { using B::f; };
    void f(D d) { &d.f; }
    === cut here ===

    This patch makes build_class_member_access_expr and cp_build_addr_expr_1
handle
    such overloads, and fixes the PR.

    Successfully tested on x86_64-pc-linux-gnu.
