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.

	that predicate functions are constructed.

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

	* sem_ch6.adb (Process_Formals): If a tagged formal is an
	incomplete class-wide type, the subprogram must have a delayed
	freeze even though the opertation is not a primitive of the
	type. THis ensures that the backend can recover the full view
	when elaborating the subprogram declaration.

	* exp_attr.adb (Size): Remove unnecessary check for types with

	* sem_ch4.adb (Extended_Primitive_Ops): Exclude overriding

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

	* sem_ch3.adb (Analyze_Component_Declaration): If the component is
	an unconstrained synchronized type with discriminants, create a
	constrained default subtype for it, so that the enclosing record
	can be given the proper size.
	* sem_util.adb (Build_Default_Subtype): If the subtype is created
	for a record discriminant, do not analyze the declarztion at
	once because it is added to the freezing actions of the enclosing
	record type.
