	Add local variables Ref_Depends and Ref_Global. Analyze
	pragmas Refined_Global and Refined_Depends in that order.

	Global. Analyze pragmas Global and Depends in that order.
	* sem_ch7.adb (Analyze_Package_Body_Helper): Package
	bodies now have a contract. Move the analysis of the aspect
	specifications after the defining entity has been decorated.
	(Analyze_Package_Declaration): Packages now have a contract. Move

	(Check_Declaration_Order): New routine.
	(Check_Test_Case): Alphabetized.
	* sem_prag.ads (Analyze_Initializes_In_Decl_Part): New routine.
	* sem_util.adb (Add_Contract_Item): Rename formal Subp_Id
	to Id. This routine can now support contracts on packages and
	package bodies.
	* sem_util.ads (Add_Contract_Item): Rename formal Subp_Id to
