2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Analyze_Object_Declaration): New function
	Has_Delayed_Aspect, used to defer resolution of an aggregate
	expression when the object declaration carries aspects Address
	and/or Alignment.
	* freeze.adb (Freeze_Object_Declaration): New subsidiary procedure
	to Freeze_Entity.  In addition to the previous processing steps
	at the freeze point of an object, this procedure also handles
	aggregates in object declarations, when the declaration carries
	delayed aspects that require that the initialization of the
	object be attached to its freeze actions.

	* sem_ch6.adb (Analyze_Subprogram_Declaration): Following
	AI12-0147, null procedures and expression functions are allowed
	in protected bodies.
