(vect_estimate_min_profitable_iters): Likewise. * tree-vect-stmts.c (vect_model_promotion_demotion_cost): New function. (vect_model_store_cost): Use vec_perm rather than vector_stmt for statement cost. (vect_model_load_cost): Likewise. (vect_get_load_cost): Likewise; add dump logic for explicit realigns.
