  Test that Atomics.wait returns the right result when it was awoken before
  a timeout
info: |
  Atomics.wait( typedArray, index, value, timeout )

  2.Let i be ? ValidateAtomicAccess(typedArray, index).
    ...
      2.Let accessIndex be ? ToIndex(requestIndex).

      9.If IsSharedArrayBuffer(buffer) is false, throw a TypeError exception.
        ...
          3.If bufferData is a Data Block, return false

          If value is undefined, then
          Let index be 0.
