2016-08-18  Richard Biener  <rguenther@suse.de>

	* tree-pass.h (make_pass_materialize_all_clones): Declare.
	* ipa.c (pass_data_materialize_all_clones, pass_materialize_all_clones,
	make_pass_materialize_all_clones): New simple IPA pass encapsulating
	clone materialization.
	* passes.def (all_late_ipa_passes): Start with
	pass_materialize_all_clones.
	* cgraphunit.c (symbol_table::compile): Remove call to
	materialize_all_clones.
	* tree-into-ssa.c: Include statistics.h.
	(update_ssa): Count number of times we do incremental/rewrite
	SSA update.
