    c++: Fix ICE in check_local_shadow with enum [PR95560]

    Another indication that perhaps this warning is emitted too early.  We
    crash because same_type_p gets a null type: we have an enumerator
    without a fixed underlying type and finish_enum_value_list hasn't yet
    run.  So check if the type is null before calling same_type_p.

            PR c++/95560
            * name-lookup.c (check_local_shadow): Check if types are
            non-null before calling same_type_p.

            * g++.dg/warn/Wshadow-local-3.C: New test.
