2011-10-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Earlier): make available globally. If both
	nodes have the same sloc, the freeze node that does not come
	from source is the later one.
	(True_Parent): Make available globally.
	(Previous_Instance): Subsidiary of
	Insert_Freeze_Node_For_Instance, to check whether the generic
	parent of the current instance is declared within a previous
	instance in the same unit or declarative  part, in which case the
	freeze nodes of both instances must appear in order to prevent
	elaboration problems in gigi.
	* sem_ch12.adb (Insert_Freeze_Node_For_Instance): A stub is a
	freeze point, and the freeze node of a preceding instantiation
	must be inserted before it.

	Raise_From_Controlled_Operation and update its associated comment.
	* a-fihema.ads, a-fihema.adb: New GNAT unit.
	Ada.Finalization.Heap_Management provides key functionality
	associated with controlled objects on the heap, their creation,
	finalization and reclamation. Type Finalization_Collection is
	effectively a wrapper which sits ontop of a storage pool and performs
	all necessary bookkeeping for all the objects it contains. Each
	access-to-controlled or access-to-class-wide type receives a collection
	as part of its expansion. The compiler generates buffer code and
	invokes Allocate / Deallocate to create and destroy allocated
	controlled objects.

	fields Prev and Next.
	* ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
	A library unit with at least one controlled object on the library level
	has a special finalizer which is invoked by the binder. To signal this,

	associated comment on field usage.
	* a-tags.adb (Get_RC_Offset): Removed.
	(Needs_Finalization): New routine.
	* a-tags.ads: Update the structure of the GNAT dispatch tables.
	Dispatch tables now carry field Needs_Finalization which provides
	runtime indication whether a type is controlled or has controlled
	components or both. Remove field RC_Offset.
	(Get_RC_Offset): Removed along with its associated pragma Export.
	Since tagged types with controlled components no longer carry hidden
	field _controller, the special mechanism to retrieve its location is no
