	* sem_prag.adb (Analyze_Contract_Case): New routine.
	(Analyze_Pragma): Aspect/pragma Contract_Cases can
	now be associated with a library level subprogram.
	Add circuitry to detect illegal uses of aspect/pragma Contract_Cases
	in a subprogram body.
	(Chain_Contract_Cases): Rename formal parameter Subp_Decl to
	Subp_Id. Remove local constant Subp. The entity of the subprogram
	is now obtained via the formal paramter.
