	for aliased constant objects.

	* exp_util.adb (Following_Address_Clause): Use new Name_Table
	boolean flag set by parser to avoid the search if there is no
	address clause anywhere for the name.
	* namet.adb (Name_Enter): Initialize Boolean_Info flag
	(Name_Find): ditto (Reinitialize): ditto (Get_Name_Table_Boolean):
	New function (Set_Name_Table_Boolean): New procedure
	* namet.ads: Add and document new Boolean field in name table
	(Get_Name_Table_Boolean): New function.
	(Set_Name_Table_Boolean): New procedure.
	* par-ch13.adb (P_Representation_Clause): Set Name_Table boolean
	flag for an identifier name if we detect an address clause or
	use-at clause for the identifier.
	* sem_ch3.adb (Analyze_Object_Declaration): Remove comment about
	Following_Address_Clause since this function is now optimized
	and is not a performance concern.
	* sem_prag.adb (Analyze_Pragma, case Elaborate): In SPARK
	mode, pragma Elaborate is now allowed, but does not suppress
	elaboration checking.
