	* dwarf2out.c (function_possibly_abstracted_p): New static function.
	(gen_subprogram_die): Use it function_possibly_abstracted_p in lieu of
	cgraph_function_possibly_inlined_p.
	(gen_inlined_subroutine_die): Return if the origin is to be ignored.
	(process_scope_var): Do not emit concrete instances of abstracted
	nested functions from here.
	(gen_decl_die): Emit the abstract instance if the function is possibly
	abstracted and not only possibly inlined.
	(dwarf2out_finish): Find the first non-abstract parent instance and
	attach concrete instances on the limbo list to it.
