tree-ssa-propagate.h (substitute_and_fold): Adjust prototype. 

2016-10-18  Richard Biener  <rguenther@suse.de>

	* tree-ssa-propagate.h (substitute_and_fold): Adjust prototype.
	* tree-ssa-propagate.c (ssa_prop_fini): Remove final BB_VISITED
	clearing.
	(substitute_and_fold_dom_walker): Adjust constructor.
	(substitute_and_fold_dom_walker::before_dom_children): Remove
	do_dce flag and handling (always true).
	(substitute_and_fold): Likewise.
	* tree-vrp.c (vrp_finalize): Adjust.
	(execute_early_vrp): Remove final BB_VISITED clearing.
	* tree-ssa-ccp.c (ccp_finalize): Adjust.
	* tree-ssa-copy.c (fini_copy_prop): Likewise.
	* ira.c (ira): Call clear_bb_flags.
