	* exp_ch13.adb: Add with and use clause for Targparm;
	(Expand_N_Free_Statement): Prevent the generation of a custom
	Deallocate on .NET/JVM targets since this requires pools and address
	arithmetic.
	* exp_ch4.adb (Expand_Allocator_Expression): When compiling for
	.NET/JVM targets, attach the newly allocated object to the access
	type's finalization collection. Do not generate a call to
	Set_Finalize_Address_Ptr on .NET/JVM because this routine does not
	exist in the runtime.
	(Expand_N_Allocator): When compiling for .NET/JVM targets, do not
	create a custom Allocate for object that do not require initialization.
	Attach a newly allocated object to the access type's finalization
	collection on .NET/JVM.
	* exp_ch5.adb (Make_Tag_Ctrl_Assignment): Add special processing for
	assignment of controlled types on .NET/JVM. The two hidden pointers
	Prev and Next and stored and later restored after the assignment takes
	place.
	* exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized
	kludge for .NET/JVM to recognize a particular piece of code coming from
	Heap_Management and change the call to Finalize into Deep_Finalize.
	* exp_ch7.adb (Build_Finalization_Collection): Allow the creation of
	finalization collections on .NET/JVM only for types derived from
	Controlled. Separate the association of storage pools with a collection
	and only allow it on non-.NET/JVM targets.
	(Make_Attach_Call): New routine.
	(Make_Detach_Call): New routine.
	(Process_Object_Declarations): Suppress the generation of
	build-in-place return object clean up code on .NET/JVM since it uses
	pools.
	* exp_ch7.ads (Make_Attach_Call): New routine.
	(Make_Detach_Call): New routine.
	* exp_intr.adb Add with and use clause for Targparm.
	(Expand_Unc_Deallocation): Detach a controlled object from a collection
	on .NET/JVM targets.
	* rtsfind.ads: Add entries RE_Attach, RE_Detach and
	RE_Root_Controlled_Ptr to tables RE_Id and RE_Unit_Table.
	* snames.ads-tmpl: Add name Name_Prev. Move Name_Prev to the special
	names used in finalization.

	* a-fihema.adb: Add with and use clauses for System.Soft_Links.
	(Attach, Detach): Lock the current task when chaining an object onto a
	collection.
