re PR tree-optimization/41497 (apparent integer wrong code bug) 

	PR tree-optimization/41497
	* tree-scalar-evolution.c (analyze_evolution_in_loop): Return
	chrec_dont_know if the evolution function returned by follow_ssa_edge
	is constant in the analyzed loop and is not compatible with the
	initial value before the loop.
	* tree-chrec.h (no_evolution_in_loop_p): Call STRIP_NOPS.

	* gcc.dg/tree-ssa/pr41497.c: New.
