Reason for revert:
Still blows up on the main waterfall even after Jakob's fix:

Original issue's description:
> [turbofan] ChangeFloat64ToTagged shouldn't canonicalize.
>
> This matches current Crankshaft/fullcodegen behavior more closely and
> thus reduces the chances that we run into unnecessary polymorphism due
> to the field representation tracking in our object model.
