	PR tree-optimization/50969
	* tree-vect-stmts.c (vect_model_store_cost): Correct statement cost to
	use vec_perm rather than vector_stmt.
	(vect_model_load_cost): Likewise.
	* config/i386/i386.c (ix86_builtin_vectorization_cost): Change cost of
	vec_perm to be the same as other vector statements.
	* config/rs6000/rs6000.c (rs6000_builtin_vectorization_cost): Revise
	cost of vec_perm for TARGET_VSX.
