	* exp_util.adb (Safe_Prefixed_Reference): Do not consider safe an
	in-mode parameter whose type is an access type since it can be used to
	modify its designated object. Enforce code that handles as safe an
	access type that is not access-to-constant but it is the result of a
	previous removal of side-effects.
	(Remove_Side_Effects): Minor code reorganization of cases which require
	no action. Done to incorporate documentation on new cases uncovered
	working in this ticket: no action needed if this routine was invoked
	too early and the nodes are not yet decorated.
	* sem_res.adb (Resolve_Slice): Minor code cleanup replacling two calls
	to routine Remove_Side_Effects by calls to Force_Evaluation since they
	were issued with actuals that are implicitly provided by
	Force_Evaluation.
