Add support for async for. Issue #124

Browse Source 
Ignore 'boilerplate' opcodes that set up the async iteration logic internally (https://www.python.org/dev/peps/pep-0492/#asynchronous-iterators-and-async-for) - We don’t need any of this as GET_AITER is enough to tell us that we are in an `async for`.
