tree-ssa-loop-niter.h (estimate_numbers_of_iterations): Take struct function as arg.

2017-06-19  Richard Biener  <rguenther@suse.de>

	* tree-ssa-loop-niter.h (estimate_numbers_of_iterations): Take
	struct function as arg.
	(estimate_numbers_of_iterations): Export overload with loop arg.
	(free_numbers_of_iterations_estimates_loop): Use an overload of
	free_numbers_of_iterations_estimates instead.
	* tree-cfg.c (remove_bb): Adjust.
	* tree-cfgcleanup.c (remove_forwarder_block_with_phi): Likewise.
	* tree-parloops.c (gen_parallel_loop): Likewise.
	* tree-ssa-loop-ivcanon.c (canonicalize_induction_variables):
	Likewise.
	(tree_unroll_loops_completely): Likewise.
	* tree-ssa-loop-niter.c (estimate_numbers_of_iterations_loop):
	Use an overload instead and export.
	(estimated_loop_iterations): Adjust.
	(max_loop_iterations): Likewise.
	(likely_max_loop_iterations): Likewise.
	(estimate_numbers_of_iterations): Take struct function as arg
	and adjust.
	(loop_exits_before_overflow): Adjust.
	(free_numbers_of_iterations_estimates_loop): Use an overload.
	* tree-vect-loop.c (vect_analyze_loop_form): Adjust.
	* tree-vectorizer.c (vect_free_loop_info_assumptions): Likewise.
