        * ipa.c (dissolve_same_comdat_group_list): New function.
        (function_and_variable_visibility): Call
        dissolve_same_comdat_group_list when comdat group contains external or
        newly local nodes.
        * cgraphunit.c (verify_cgraph_node): Verify that same_comdat_group
        lists are circular and that they contain only DECL_ONE_ONLY nodes.
