+       to const_rtx.
+       (combine_reaching_defs): Likewise.
+       (struct re_info): Remove.
+       (add_removable_extension): Remove x and data arguments,
+       add insn, insn_list and def_map.  Use the arguments directly
+       instead of using struct re_info.
+       (find_removable_extensions): Don't call add_removable_extension
+       through note_stores, instead just call it with single_set
+       result if non-NULL.
+       (find_and_remove_re): Pass curr_cand->expr instead of
+       PATTERN (curr_cand->insn) as set_pat argument to
+       combine_reaching_defs.
