This is problematic and needs to be resolved. The typed array spec defines
Uint8ClampedArray as a subtype of Uint8Array for good reason -- if there are
APIs that take Uint8Array, they should also take Uint8ClampedArray. This issue
needs to be raised with TC39.

This is a major compatibility problem. BYTES_PER_ELEMENT must be defined as a
property on the constructor function, not on the prototype, per the typed array
spec. The ES6 spec must be updated.
