Turn Scope::locals_ into a ThreadedList This turns the ZoneList with minimum 6 words overhead into a linked list through variables, using 2 words for the empty list. Additionally the average number of pointers per entry goes down to the optimal 1 per variable that's in a list. This does introduce 1 pointer unnecessary overhead for dynamic variables. If that becomes a problem we could distinguish between variables in lists and variables not in lists. We can distinguish them at construction-time.
