  Throws a TypeError if typedArray.buffer is not a SharedArrayBuffer
info: |
  Atomics.waitAsync( typedArray, index, value, timeout )

  1. Return DoWait(async, typedArray, index, value, timeout).

  DoWait ( mode, typedArray, index, value, timeout )

  1. Let buffer be ? ValidateSharedIntegerTypedArray(typedArray, true).

  ValidateSharedIntegerTypedArray ( typedArray [ , waitable ] )

  5. If waitable is true, then
    a. If typeName is not "Int32Array" or "BigInt64Array", throw a TypeError exception.
