  Throws a TypeError if value arg is a Symbol
info: |
  Atomics.waitAsync( typedArray, index, value, timeout )

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

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

  5. Otherwise, let v be ? ToInt32(value).

  ToInt32(value)

  1.Let number be ? ToNumber(argument).

    Symbol --> Throw a TypeError exception.
