	Fix PR debug/19124
	* dwarf2out.c (concat_loc_descriptor): We don't know we can use
	fbreg, so we have to assume we can't.
	(loc_descriptor_from_tree_1): Ditto.
	(containing_function_has_frame_base): New function.
	(add_location_or_const_value_attribute): Use it.
	Also try to generate a frame_base from a single element location
	list.
