	* sem_ch5.adb (Analyze_Iteration_Scheme.Uses_Secondary_Stack): New
	function. Used to be more precise when we generate a variable plus one
	assignment to remove side effects in the evaluation of the Bound
	expressions.
	(Analyze_Iteration_Scheme): Clean attribute analyzed in all the nodes
	of the bound expression to force its re-analysis and thus expand the
	associated transient scope (if required). Code cleanup replacing the
	previous code that declared the constant entity by an invocation to
	routine Force_Evaluation which centralizes this work in the frontend.
