	* freeze.adb (Freeze_Entity): Remove check for preelaborable
	initialization of a full view. This is moved to
	Analyze_Package_Specification.

	* sem_ch7.adb (Analyze_Package_Specification): Add check for
	preelaborable initialization of a full view in entity loop.
	(Uninstall_Declarations): If entity is a use-visible compilation unit,
	its child units are use-visible only if they are visible child units.

	* sem_util.adb (Is_Preelaborable_Expression): New function to determine
	whether an expression can be used within a type declaration that
	requires preelaborable init.
	(Check_Components): Replace inline code that does partial checking for
	preelaborable default expressions with call to
	Is_Preelaborable_Expression.
	(Has_Preelaborable_Initialization): In the case of a generic actual
	subtype, (that is, Is_Generic_Actual is True), return the result of
	applying Has_Preelaborable_Initialization to the generic actual's base
	type.
