Reorder fields. (alloc_iv, set_iv): New parameter. (determine_biv_step): Delete. (find_bivs): Inline original determine_biv_step. Pass new argument to set_iv. (idx_find_step): Use no_overflow information for conversion. * tree-scalar-evolution.c (analyze_scalar_evolution_in_loop): Let resolve_mixers handle folded_casts. (instantiate_scev_name): Change bool parameter to bool pointer. (instantiate_scev_poly, instantiate_scev_binary): Ditto. (instantiate_array_ref, instantiate_scev_not): Ditto. (instantiate_scev_3, instantiate_scev_2): Ditto. (instantiate_scev_1, instantiate_scev_r): Ditto. (instantiate_scev_convert, ): Change parameter. Pass argument to chrec_convert_aggressive. (instantiate_scev): Change argument. (resolve_mixers): New parameter and set it.
