Yang Guo 9c6bc7afc0 Leave spaces between instance types. 
We used to frequently break the ABI when we introduced new instance
types because some instance types are hard-coded in v8.h.

Now that we have more instance types available, we can leave some
room to anticipate future new instance types.

Also take this opportunity to reorder some instance types.
