[Vm-dev] Minor change for understanding

I submit a really small change for make some code more easy to intercept class access in VM.
I do crappy think with class pointer and i would like to indirect the access to the class.

I just create a method change reference of 4 new one. I have the feeling that make the structure more understandable.
with this change i was able to intercept all class access on my experimental VM by changing 3 method.
I run tiny benchmark for see if the change add overhead on class access. I don't find any overhead.
