  Use prototype from new target if it's an Object
info: |
  22.2.4.3 TypedArray ( typedArray )

  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 has a [[TypedArrayName]] internal slot.

  ...
  4. Let O be ? AllocateTypedArray(constructorName, 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.
