Throws a TypeError if index arg can not be converted to an Integer
info: |
Atomics.waitAsync( typedArray, index, value, timeout )
1. Return DoWait(async, typedArray, index, value, timeout).
DoWait ( mode, typedArray, index, value, timeout )
6. Let q be ? ToNumber(timeout).
Symbol --> Throw a TypeError exception.
