	* sem_ch13.adb (Build_Predicate_Functions): The expression for
	the predicate is side-effect free if it does not contain any
	variable references.

	* a-convec.adb ("="): Previous version depended
	on "=" composing, but that doesn't quite work -- we want the "="
	operator passed in to the generic. So we need a loop after all.

	* sem_util.adb (Is_Object_Reference): Attribute 'Loop_Entry produces
	an object.
	* sem_ch6.adb: Minor fix in comment.
