* a-except.adb, a-except-2005.adb (Raise_From_Controlled_Operation):

* 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.

field _controller, the special mechanism to retrieve its location is no
longer needed.
