	* einfo.ads, einfo.adb (Incomplete_Actuals): New attribute of
	package instantiations. Holds the list of actuals in the instance
	that are incomplete types, to determine where the corresponding
	instance body must be placed.
	* sem_ch6.adb (Conforming_Types): An incomplete type used as an
	actual in an instance matches an incomplete formal.
	* sem_disp.adb (Check_Dispatching_Call): Handle missing case of
	explicit dereference.
	(Inherited_Subprograms): In the presence of a limited view there
	are no subprograms to inherit.
	* sem_ch12.adb (Preanalyze_Actuals): Build list of incomplete
	actuals of instance, for later placement of instance body and
	freeze nodes for actuals.
	(Install_Body): In the presence of actuals that incomplete types
	from a limited view, the instance body cannot be placed after
	the declaration because full views have not been seen yet. Any
	use of the non-limited views in the instance body requires
	the presence of a regular with_clause in the enclosing unit,
	and will fail if this with_clause is missing.  We place the
	instance body at the beginning of the enclosing body, which is
	the unit being compiled, and ensure that freeze nodes for the
	full views of the incomplete types appear before the instance.
