	* exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
	inserted cleanup code appropriately for GDB use.
	(Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
	exception handler for Deep_Adjust or Deep_Finalize.
	(Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
	Raise_From_Controlled_Operation is available, use a call to that
	subprogram instead of a plain "raise Program_Error" node to raise
	Program_Error if an exception is propagated from an Adjust or Finalize
	operation.
	(Insert_Actions_In_Scope_Around): If the statement to be wrapped
	appears in the optional statement list of a triggering alternative, the
	scope actions can be inserted directly there, and not in the list that
	includes the asynchronous select itself.
