nit: Since this is an unhandlified method, I would vote for it being a true
member method instead of a static helper. I am thinking along the lines of
"Cell* GetCall(int cell_index)" here.

Also it seems this is an internal helper. Would it make sense to make it
private?

   static Handle<Object> LoadVariable(Handle<Module> module, int cell_index);
   static void StoreVariable(Handle<Module> module, int cell_index,
                             Handle<Object> value);
