	* sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
	node between access types, freeze the designated type as well,

	* sem_res.adb (In_Instance_Code): New predicate in
	Valid_Conversion, to determine whether a type conversion appears
	as (or within) an actual for a formal object.  Type conversions
	in instances are not rechecked in Valid_Conversion because
	visibility changes between generic location andi instance may
	lead to spurious errors, but conversions within an actual must be
	fully checked, and they are not fully resolved when pre-analyzing
	the actuals.
