	* exp_ch7.adb (Find_Final_List): Change the test for generating a
	selected component from an access type's Associated_Final_Chain to
	check for the presence of that field, rather than assuming it exists
	for all named access types.
	(Make_Clean): New formal Chained_Cleanup_Action allowing to specify a
	procedure to call at the end of the generated cleanup procedure.
	(Expand_Cleanup_Actions): When a new cleanup procedure is generated, and
	and an At_End_Proc already exists in the handled sequence of statements
	for which cleanup actions are being expanded, the original cleanup
	action must be preserved.
