Fix simulator bitrot

:exclamation: This is work in progress, doesn't need to be merged yet.
For the moment, it is just to keep track of things.

With the following code snipped it is possible to run a recent Pharo image on the simulator.

```Smalltalk
| sim |
InterpreterStackPage initialize.
StackInterpreterSimulator initializeWithOptions: Dictionary new.
sim :=  StackInterpreterSimulator new.
sim openOn: 'Pharo.image'. 
sim openAsMorph.
sim inspect.
1 to: 500 do: [:i |
	World doOneCycleNow.
	sim runForNBytes: 100000 ].
```
