	* sem_ch6.adb (Analyze_Expression_Function): If expression function
	is completion and return type is an access type do not freeze
	designated type: this will be done in the process of freezing
	the expression if needed.
	(Freeze_Expr_Types): Check whether type is complete before
	creating freeze node, to provide a better error message if
	reference is premature.
	* sem_ch13.adb (Check_Indexing_Functions): Ignore inherited
	functions created by type derivations.
