  Throws a TypeError if targetBuffer is detached on ToInteger(offset)
info: |
  22.2.3.23.2 %TypedArray%.prototype.set(typedArray [ , offset ] )

  1. Assert: typedArray has a [[TypedArrayName]] internal slot. If it does not,
  the definition in 22.2.3.23.1 applies.
  ...
  6. Let targetOffset be ? ToInteger(offset).
  ...
  8. Let targetBuffer be the value of target's [[ViewedArrayBuffer]] internal
  slot.
  9. If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception.
  ...
