org.apache.derby.iapi.services.compiler.MethodBuilder.methodReturn()
Return from a method, optionally with a value. Must only be called if zero or one item exists on the stack. If the stack contains a single value then that is popped and used as the returned value.
```
 Stack value => :empty: or Stack :empty: => :empty:
