Return abrupt completion from typedArray argument's buffer.constructor's value

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.
...
17. If SameValue(elementType, srcType) is true, then
a. Let data be ? CloneArrayBuffer(srcData, srcByteOffset).
...
24.1.1.4 CloneArrayBuffer ( srcBuffer, srcByteOffset [ , cloneConstructor ] )
...
2. If cloneConstructor is not present, then
a. Let cloneConstructor be ? SpeciesConstructor(srcBuffer, %ArrayBuffer%).
...
7.3.20 SpeciesConstructor ( O, defaultConstructor )
...
2. Let C be ? Get(O, "constructor").
...
4. If Type(C) is not Object, throw a TypeError exception.
