	* freeze.ads, freeze.adb (Freeze_Entity, Freeze_Before): Add
	boolean parameter to determine whether freezing an overloadable
	entity freezes its profile as well. This is required by
	AI05-019. The call to Freeze_Profile within Freeze_Entity is
	conditioned by the value of this flag, whose default is True.
	* sem_attr.adb (Resolve_Attribute, case 'Access): The attribute
	reference freezes the prefix, but it the prefix is a subprogram
	it does not freeze its profile.
