	* graphite-clast-to-gimple.c (compute_bounds_for_level): Call
	psct_dynamic_dim.
	(translate_clast_for_loop): Pass loop level to dependency_in_loop_p.
	(gcc_type_for_iv_of_clast_loop): Update use of level.
	(gloog): Start counting nesting level from 0.
	* graphite-clast-to-gimple.h (get_scattering_level): Removed.
	* graphite-dependences.c (graphite_carried_dependence_level_k): Call
	psct_dynamic_dim on level.
