+  1. Let O be the this value.
+  2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
+  3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
+  4. If IsDetachedBuffer(O) is true, throw a TypeError exception.
+  5. If newLength is undefined, let newByteLength be
+     O.[[ArrayBufferByteLength]].
+  6. Else, let newByteLength be ? ToIntegerOrInfinity(newLength).
