	* sem_util.adb (Mark_Coextensions): If the expression in the allocator
	for a coextension in an object declaration is a concatenation, treat
	coextension as dynamic.

	* sem_ch3.adb (Add_Internal_Interface_Entities): Ensure that the
	internal entities are added to the scope of the tagged type.
	(Derive_Subprograms): Do not stop derivation when we find the first
	internal entity that has attribute Interface_Alias. After the change
	done to Override_Dispatching_Operations it is no longer true that
	these primirives are always located at the end of the list of
	primitives.
	* einfo.ads (Primitive_Operations): Add documentation.
	* exp_disp.adb (Write_DT): Improve output adding to the name of the
	primitive a prefix indicating its corresponding tagged type.
	* sem_disp.adb (Override_Dispatching_Operations): If the overridden
	entity covers the primitive of an interface that is not an ancestor of
	this tagged type then the new primitive is added at the end of the list
	of primitives.  Required to fulfill the C++ ABI.
