	* sem_ch6.adb (Analyze_Function_Return): Set Referenced on return
	objects, since these are implicitly referenced by the return statement.
	* sem_warn.adb (Warn_On_Unreferenced_Entity): No longer a need to test
	Is_Return_Object in this procedure, as return objects will never make
	it here since they're now marked as Referenced.

	* exp_ch2.adb, sem_util.adb, sem_util.ads: Minor reformnatting
