Willi Goesgens 202636cee0 Refactor Optimizer ordering 
- create enum with the different steps named
  - unify numbering scheme
  - deploy enum to all places where int level was used
  - add passN enum so you can jump to a Pass when calling addPlan

useIndexForSort:
  - remove inline deletion of dependend nodes of our (removed) sortnode
  - redirect to pass #5 so now possible obsolete CalculaionNodes are removed by the removeUnnecessaryCalculationsRule
