[27/46] Remove duplicated stmt_vec_info lookups
Various places called vect_dr_stmt or vinfo_for_stmt multiple times on the same input. This patch makes them reuse the earlier result. It also splits a couple of single vinfo_for_stmt calls out into separate statements so that they can be reused in later patches. 2018-07-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-data-refs.c (vect_analyze_data_ref_dependence) (vect_slp_analyze_node_dependences, vect_analyze_data_ref_accesses) (vect_permute_store_chain, vect_permute_load_chain) (vect_shift_permute_load_chain, vect_transform_grouped_load): Avoid repeated stmt_vec_info lookups. * tree-vect-loop-manip.c (vect_can_advance_ivs_p): Likewise.
