	* sem_ch13.adb: Minor reformatting and typo fix.

	* par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
	Iterated_Component_Association is a named association in an
	array aggregate.
	* sem_aggr.adb (Resolve_Iterated_Component_Association): New
	procedure, subsidiary of Resolve_Array_Aggregate, to analyze
	and resolve the discrete choices and the expression of the
	new construct.
	* sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
	Loop_Actions and Box_Present are attributes of
	N_Iterated_Component_Association nodes. Box_Present is always
	False in this case.
	* sprint.adb (Sprint_Node): An Iterated_Component_Association
	has a Discrete_Choices list, as specified in the RM. A
	Component_Association for aggregate uses instead a Choices list.
	We have to live with this small inconsistency because the new
	construct also has a defining identifier, and there is no way
	to merge the two node structures.
