Log message:
	* tree-scalar-evolution.c: (get_loop_exit_condition): Exposed to
	external usage.
	* tree-scalar-evolution.h: (get_loop_exit_condition): Exposed to
	external usage.
	* tree-vectorizer.c: (vect_is_simple_iv_evolution): Additional argument
	to control how strict this function would be.
	(vect_create_index_for_array_ref): Invoke vect_is_simple_iv_evolution
	with "strict" set to true.
	(vect_transform_loop_bound): More general loop bound transformation
	scheme, independent of the loop exit condition form.
	(vect_analyze_scalar_cycles): Invoke vect_is_simple_iv_evolution with
	"strict" set to false.
	(vect_get_loop_niters): Use monev utilities/precomputed info -
	loop->nb_iterations and get_loop_exit_condition.
