- Introduce the new union type UnionType<T1,T2>, used for Number and Numeric. Similarly, PairType<T1,T2> is used for a Turbofan operation with two results. Further details in the design doc: https://docs.google.com/document/d/10foP3m7SDWyFfbda96iEJ_XYOLQdd32AeoP8SD1cTcs/edit#heading=h.bghdno28mr7u - Allow to derive the MachineType from a static type. This allows to select the right MachineType when performing a load/store. - Disallow casts (UncheckedCast() or CAST()) when the target and origin type have no overlap. New cast ReinterpretCast() is an UncheckedCast without this check. - Caveat of this CL: Checked casts (CAST()) are not possible for UnionType<T1,T2> with the exception of Number (due to the existence of Number in OBJECT_TYPE_LIST and the existence of an IsNumber() function in the runtime).
