rtti.c (tinfo_base_init): Use build_constructor instead of build_constructor_from_list. 

	* rtti.c (tinfo_base_init): Use build_constructor instead of
	build_constructor_from_list.  Don't cons a tree node for
	returning.
	(generic_initializer): Use build_constructor_single instead of
	build_constructor_from_list.
	(ptr_initializer): Use build_constructor instead of
	build_constructor_from_list
	(ptm_initializer): Likewise.
	(class_initializer): Likewise.  Take varargs instead of TRAIL.
	(get_pseudo_ti_init): Adjust calls to class_initializer.  Use
	build_constructor instead of build_constructor_from_list.
