	* sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
	dereference of a local object R created as a reference to another
	object O, use the access level of O.
	(Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
	rather than local Same_Formal_Type, to check whether protected operation
	overrides an inherited one.
	(Same_Formal_Type): New predicate, used when matching signatures of
	overriding synchronized operations, to handle the case when a formal
	has a type that is a generic actual.
	(Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
	predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
	(Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
	syntactic ambiguities involving indexing of function calls that return
	arrays.
	(Abstract_Interface_List): New subprogram that returns the list of
	abstract interfaces associated with a concurrent type or a
	concurrent record type.
	(Interface_Present_In_Parent): New subprogram used to check if a
	given type or some of its parents implement a given interface.
	(Collect_Abstract_Interfaces): Add support for concurrent types
	with interface types.
	(Has_Abstract_Interfaces): Add support for concurrent types with
	interface types.
	(Is_Parent): New subprogram that determines whether E1 is a parent
	of E2. For a concurrent type its parent is the first element of its
	list of interface types; for other types this function provides the
	same result than Is_Ancestor.
	(Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
	(Collect_Synchronized_Interfaces): Removed because the subprogram
	Collect_Abstract_Interfaces provides this functionality.
	(Collect_Abstract_Interfaces): Minor update to give support to
	concurrent types and thus avoid undesired code duplication.
	(Get_Subprogram_Entity): Handle entry calls.
	(May_Be_Lvalue): Include actuals that appear as in-out parameters in
	entry calls.
	(Enter_Name): Do not give -gnatwh hiding warning for record component
	entities, they never result in hiding.
