description: >
  Unreachable abrupt from Get(O, "length") as [[ArrayLength]] is returned.

  22.2.3.5 %TypedArray%.prototype.copyWithin (target, start [ , end ] )

  %TypedArray%.prototype.copyWithin is a distinct function that implements the
  same algorithm as Array.prototype.copyWithin as defined in 22.1.3.3 except
  that the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length" and the actual copying of values in step 12
  must be performed in a manner that preserves the bit-level encoding of the
  source data.

  22.1.3.3 Array.prototype.copyWithin (target, start [ , end ] )

  1. Let O be ? ToObject(this value).
  2. Let len be ? ToLength(? Get(O, "length")).
