tree-pass.h (execute_pass_list): Adjust prototype.

2014-04-28  Richard Biener  <rguenther@suse.de>

	* tree-pass.h (execute_pass_list): Adjust prototype.
	* passes.c (pass_manager::execute_early_local_passes):
	Adjust.
	(do_per_function): Change callback signature, push all actual
	work to the callbals.
	(do_per_function_toporder): Likewise.
	(execute_function_dump): Adjust.
	(execute_function_todo): Likewise.
	(clear_last_verified): Likewise.
	(verify_curr_properties): Likewise.
	(update_properties_after_pass): Likewise.
	(execute_pass_list_1): Split out from ...
	(execute_pass_list): ... here.  Adjust.
	(execute_ipa_pass_list): Likewise.
	* cgraphunit.c (cgraph_add_new_function): Adjust.
	(analyze_function): Likewise.
	(expand_function): Likewise.
	* cgraph.c (release_function_body): Free dominance info
	here instead of asserting it was magically freed elsewhere.
