Before this change, Slot had separate fields and bits for type info:
* cid_
* static_type_
* IsNullableBit
* IsSentinelVisibleBit
This change consolidates all these pieces into a CompileType.
Also, native Slot objects are now Zone-allocated like all other Slot objects and can contain Zone-allocated handles (such as static type).
