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.
