loop.h (total_biv_increment): Constify iv_class pointer.
* loop.h (total_biv_increment): Constify iv_class pointer.
(struct induction): Replace `mem_mode' with `mem' rtx.
* unroll.c (total_biv_increment): Constify iv_class pointer.
* loop.c (loop_giv_reduce_benefit): Derive mem mode from mem rtx.
(find_mem_givs, combine_givs_p): Likewise.
(debug_ivs, debug_iv_class, loop_ivs_dump, loop_iv_class_dump): New.
