Richard Biener 78db0e093e add vectype parameter to add_stmt_cost hook 
This adds a vectype parameter to add_stmt_cost which avoids the need
to pass down a (wrong) stmt_info just to carry this information.
Useful for invariants which do not have a stmt_info associated.

2020-05-13  Richard Biener  <rguenther@suse.de>

	* target.def (add_stmt_cost): Add new vectype parameter.
	* targhooks.c (default_add_stmt_cost): Adjust.
	* targhooks.h (default_add_stmt_cost): Likewise.
	* config/aarch64/aarch64.c (aarch64_add_stmt_cost): Take new
	vectype parameter.
	* config/arm/arm.c (arm_add_stmt_cost): Likewise.
	* config/i386/i386.c (ix86_add_stmt_cost): Likewise.
	* config/rs6000/rs6000.c (rs6000_add_stmt_cost): Likewise.

	* tree-vectorizer.h (stmt_info_for_cost::vectype): Add.
	(dump_stmt_cost): Add new vectype parameter.
	(add_stmt_cost): Likewise.
	(record_stmt_cost): Likewise.
	(record_stmt_cost): Add overload with old signature.
	* tree-vect-loop.c (vect_compute_single_scalar_iteration_cost):
	Adjust.
	(vect_get_known_peeling_cost): Likewise.
	(vect_estimate_min_profitable_iters): Likewise.
	* tree-vectorizer.c (dump_stmt_cost): Add new vectype parameter.
	* tree-vect-stmts.c (record_stmt_cost): Likewise.
	(vect_prologue_cost_for_slp_op): Remove stmt_vec_info parameter
	and pass down correct vectype and NULL stmt_info.
	(vect_model_simple_cost): Adjust.
	(vect_model_store_cost): Likewise.
