DatePrototype: In ES6, this is an Object, not a DateObject

Quoting 20.3.4:
    The Date prototype object is the intrinsic object %DatePrototype%. The Date
    prototype object is itself an ordinary object. It is not a Date instance
    and does not have a [[DateValue]] internal slot.

Aside from Symbol failures (which we expect, because we don't have a
Symbol implementation at this time), Date.prototype only has these two
failures left in ES6:

    setFullYear/new-value-time-clip in strict mode
    setFullYear/new-value-time-clip in non-strict mode
    setMonth/new-value-time-clip in strict mode
    setMonth/new-value-time-clip in non-strict mode

These seem to be related to handling of overflow conditions.
