	* lib-xref.ads, lib-xref.adb (Generate_Definition): Treat any entity
	declared within an inlined body as referenced, to prevent spurious
	warnings.
	(Output_One_Ref): If an entity renames an array component, indicate in
	the ALI file that this aliases (renames) the array. Capture as well
	function renamings that rename predefined operations.
	Add information about generic parent for package and subprogram
	instances.
	(Get_Type_Reference): For a subtype that is the renaming of an actual in
	an instantiation, use the first_subtype to ensure that we don't generate
	cross-reference information for internal types.
	For objects and parameters of a generic private type, retain the '*'
	indicator to distinguish such an entity from its type.

        * ali.ads (Xref_Entity_Record): New fields Iref_File_Num and Iref_Line,
        to store information about instantiated entities.

        * ali.adb (Scan_ALI): Add support for parsing the reference to the
        generic parent

        * xref_lib.adb (Skip_To_Matching_Closing_Bracket): New subprogram
        (Parse_Identifier_Info, Parse_Token): Add support for the generic parent
        information.
