3330 * df-problems.c (df_ru_confluence_n, df_rd_confluence_n):
3331 Corrected confluence operator to remove bits from op2 before oring

3333 (df_ru_transfer_function): Corrected test on wrong bitmap which
3334 caused infinite loop. Both of these problems were introduced in
3335 the dataflow rewrite.
