Log message:
	* combine.c (try_combine) [HAVE_cc0]: Trying to check the missed
	case 3->2 combining (combining with splitting) in which 2 is CC0
	setter/user and 3 is user. The rest of cases 2->1 and 3->2 are
	checked at the begining of the function with the aid of calling
	function 'can_combine_p'.
