Log:
    PR rtl-optimization/51978
    * ree.c (make_defs_and_copies_lists): Change set_pat type
    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.
