  Use prototype from %TypedArray% if newTarget's prototype is not an Object
info: |
  22.2.4.4 TypedArray ( object )

  This description applies only if the TypedArray function is called with at
  least one argument and the Type of the first argument is Object and that
  object does not have either a [[TypedArrayName]] or an [[ArrayBufferData]]
  internal slot.

  ...
  3. Let O be ? AllocateTypedArray(TypedArray.[[TypedArrayConstructorName]],
  NewTarget, "%TypedArrayPrototype%").
  ...

  22.2.4.2.1 Runtime Semantics: AllocateTypedArray (constructorName, newTarget,
  defaultProto [ , length ])

  1. Let proto be ? GetPrototypeFromConstructor(newTarget, defaultProto).
  2. Let obj be IntegerIndexedObjectCreate (proto, «[[ViewedArrayBuffer]],
  [[TypedArrayName]], [[ByteLength]], [[ByteOffset]], [[ArrayLength]]» ).
  ...

  9.4.5.7 IntegerIndexedObjectCreate (prototype, internalSlotsList)

  ...
  10. Set the [[Prototype]] internal slot of A to prototype.
  ...
  12. Return A.
