    Original commit message:
        Introduce a new machine operator Float64Pow that for now is backed by
        the existing MathPowStub to start the unification of Math.pow, and at
        the same time address the main performance issue that TurboFan still has
        with the imaging-darkroom benchmark in Kraken.
    
        Also migrate the Math.pow builtin itself to a TurboFan builtin and
        remove a few hundred lines of hand-written platform code for special
        handling of the fullcodegen Math.pow version.
