	* sem_ch5.adb (Analyze_Iterator_Specification): If the domain of
	iteration is an array component that depends on discriminants,
	create an actual subtype for it, because the preanalysis of the
	iterator name does not create actual subtypes of components.

	* freeze.adb (Freeze_Expression): Update the loop in charge
	of finding a proper insertion place for freeze nodes to handle
	N_Expression_With_Actions nodes.
