TypedArray implementations have a null prototype instead of the TypedArray intrinsic

[andreabergia]

This should return an object with all the various TypedArray methods defined on it (find, map, etc), but it returns undefined in rhino:

Object.getPrototypeOf(Int8Array).prototype

The following should also be true, but are not:

Object.getPrototypeOf(Int8Array).prototype !== undefined && 
  Object.getPrototypeOf(Int8Array).prototype == Object.getPrototypeOf(Uint8Array).prototype

Object.getPrototypeOf(Int8Array.prototype) === Object.getPrototypeOf(Uint8Array).prototype

Due to this, all TypedArray implementations are missing the static .from. and .of methods

Strongly consider implementing the required NativeTypedArray class using Lambdas, see #1411 (comment)
