A null value for bufferData throws a TypeError
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 ] )
2. Perform ? RequireInternalSlot(typedArray, [[TypedArrayName]]).
RequireInternalSlot ( O, internalSlot )
1. If Type(O) is not Object, throw a TypeError exception.
2. If O does not have an internalSlot internal slot, throw a TypeError exception.
