Log message:
	PR bootstrap/13848
	* cse.c (cse_cc_succs): Change the mode of the source expression
	as soon as decide we need a new mode.  Don't permit changing modes
	if we found a match in a successor block.
	(cse_condition_code_reg): Save original mode of source expression
	so that we know whether we have to change the mode in other
	insns.
	
	* gcc.dg/20040124-1.c: New test.
