	* sem_ch6.adb (Cloned_Expression): New subprogram.
	(Freeze_Expr_Types): Complete previous patch since the expression
	of an expression-function may have iterators and loops with
	defining identifiers which, as part of the preanalysis of the
	expression, may be left decorated with itypes that will not be
	available in the tree passed to the backend.
