re PR middle-end/49801 (df_live_verify_transfer_functions fails with to use of CC_REGNUM and checking enabled in rx backend)
PR middle-end/49801
* compare-elim.c (find_comparisons_in_bb): Use df_get_live_in and
df_get_live_out instead of accessing the bitmaps directly.
(execute_compare_elim_after_reload): Remove calls to df_set_flags,
df_live_add_problem and df_analyze.
