  Throws an error if buffer is detached before setting a value
info: |
  22.2.3.23.1 %TypedArray%.prototype.set (array [ , offset ] )

  1. Assert: array is any ECMAScript language value other than an Object with a
  [[TypedArrayName]] internal slot. If it is such an Object, the definition in
  22.2.3.23.2 applies.
  ...
  21. Repeat, while targetByteIndex < limit
    a. Let Pk be ! ToString(k).
    b. Let kNumber be ? ToNumber(? Get(src, Pk)).
    c. If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception.
    d. Perform SetValueInBuffer(targetBuffer, targetByteIndex, targetType,
    kNumber).
