    Original change's description:
    > Optimize TypedArraySpeciesCreate using SpeciesProtector of Array
    > 
    > If there is no constructor or species updates on Array or TypedArrays,
    > then skip lookups of constructor and species so that we can create a new
    > typed array quickly. This path makes TA.p.slice() 4x faster in fast
    > cases.
