This CL
* Makes :async_op only have two parameters: We take advantage
of the fact that errors not only have exception != null but
also stacktrace != null.
* Makes :async_op have no optional parameters. This reduces
code size significantly.
* Removes unused parameter in _awaitHelper calls
* Wrap the then callback instead of the error callback. (needed
to make optional parameters required)
This results in 2% code savings on a big g3 app.
The size of :async_op shrinks on average by 11%
