	PR ada/34149
	* sem_disp.adb (Check_Dispatching_Call): Augment existing test for
	presence of a statically tagged operand (Present (Static_Tag)) with
	test for Indeterm_Ancestor_Call when determining whether to propagate
	the static tag to tag-indeterminate operands (which forces dispatching
	on such calls).
	(Check_Controlling_Formals): Ada2005, access parameters can have
	defaults.
	(Add_Dispatching_Operation, Check_Operation_From_Private_View): do
	not insert subprogram in list of primitive operations if already there.
