VMMaker 4.15.10 - Fix 'debug it' from the menu for V3 images.

Fix primitiveChangeClass by factoring fetchClassOfNonImm: into a version for ClassicObjectMemory that calls fetchClassofNonInt: and a version for NewObjectMemory that retains the oscog implementation.

TODO: The primitive now works as expected for interpreter VM, but fetchClassOfNonImm: should be revisited for StackInterpreter on V3 image (may depend on Spur logic).
