re PR tree-optimization/57331 (ICE: tree check: expected integer_type or enumeral_type or boolean_type or real_type or fixed_point_type, have pointer_type in int_fits_type_p, at tree.c:8437)

	PR tree-optimization/57331
	* tree-vrp.c (simplify_cond_using_ranges): Don't optimize
	comparison of conversion from pointer type to integral type
	with integer.
