	* exp_ch3.adb
	(Is_Variable_Size_Array): Remove local subprogram Is_Constant_Bound.
	* sem_ch3.adb
	(Constrain_Index): Remove side effects in the evaluation of the bounds.
	* sem_ch3.ads, sem_ch3.adb
	(Is_Constant_Bound): New extended version of the subprogram that was
	previously located inside function Exp_Ch3.Is_Variable_Size_Array.
	Moved here since it is shared by routines of sem_ch3 and exp_ch3.
	* sem_aux.ads (Constant_Value): Fix typo in comment.
	* checks.adb (Generate_Index_Checks): New implementation which, for
	array objects with constant bounds, generates the runtime check
	referencing the bounds of the array type. For other cases this routine
	provides its previous behavior obtaining such values from the array
	object.
	* sem_res.adb (Set_Slice_Subtype): Link a copied range subtree with its
	parent type.
	* atree.adb (New_Copy): Reset flag Is_Overloaded in the new copy since
	we cannot have semantic interpretations of the new node.
