	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.
