description: Throws a TypeError if comparefn detaches the object buffer
info: |

  When the TypedArray SortCompare abstract operation is called with two
  arguments x and y, the following steps are taken:

  ...
  2. If the argument comparefn is not undefined, then
    a. Let v be ? Call(comparefn, undefined, « x, y »).
    b. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
    ...
