        PR rtl-optimization/25799 
        * df-problems.c (df_ru_confluence_n, df_rd_confluence_n):
        Corrected confluence operator to remove bits from op2 before oring
        with op1 rather than removing bits from op1.
        (df_ru_transfer_function): Corrected test on wrong bitmap which
        caused infinite loop.  Both of these problems were introduced in
        the dataflow rewrite.
