Make 'loop iv compare' heuristics scanning more precise

	* gcc.dg/predict-1.c: Distinguish between "loop iv compare"
	and "guess loop iv compared" heuristics.
	* gcc.dg/predict-2.c: Likewise.
	* gcc.dg/predict-3.c: Likewise.
	* gcc.dg/predict-4.c: Likewise.
	* gcc.dg/predict-5.c: Likewise.
	* gcc.dg/predict-6.c: Likewise.
