TypedArray accessor detection: consider entire prototype chain

TypedArray accessor detection: consider entire prototype chain

("length", "byteLength", "byteOffset"), consider the entire prototype
chain, not only the direct prototype.
This allows subclasses of TypedArrays to benefit from fast specialized
accesses.
