	* sem_attr.adb (Analyze_Attribute_Old_Result): The attributes can
	appear in the postcondition of a subprogram renaming declaration,
	when the renamed entity is an attribute reference that is a
	function (such as 'Value).
	* sem_attr.adb (Eval_Attribute): It doesn't
	need to be static, just known at compile time, so use
	Compile_Time_Known_Value instead of Is_Static_Expression.
	This is an efficiency improvement over the previous bug fix.
	* sem_ch13.adb (Analyze_One_Aspect): Use Original_Node to detect
	illegal aspects on subprogram renaming declarations that may
	have been rewritten as bodies.

	* sem_intr.adb (Errint): Do not emit error message in
	Relaxed_RM_Semantics mode.
