class.c (resolve_address_of_overloaded_function): Mark the chosen function used.

Browse Source 
* class.c (resolve_address_of_overloaded_function): Mark the
	chosen function used.
	* call.c (build_call): Make sure that a function coming in has
	been marked used already.
	* decl.c (expand_static_init): Call mark_used instead of
	assemble_external.
	* except.c (call_eh_info, do_pop_exception, expand_end_eh_spec,
	alloc_eh_object, expand_throw): Likewise.
	* init.c (build_builtin_delete_call): Likewise.
