dwarf2out.c (cu_die_list): New global. 

2016-09-27  Richard Biener  <rguenther@suse.de>

	* dwarf2out.c (cu_die_list): New global.
	(dwarf2out_finish): Walk cu_die_list instead of limbo DIEs.  Add
	main_comp_unit_die to cu_die_list if we created it.
	Move break_out_includes ...
	(dwarf2out_early_finish): ... here.  Push created CU DIEs onto
	the cu_die_list.
