PTAL

As noted on the bug, there isn't really a place for GeneratorMirror WRT async
functions, since the generator object is never exposed to the user or the
debugger (currently).

I think we may want to figure out the semantics we want and revisit that later,
but for now, a FunctionMirror test which deals with async functions might be
good. ScopeMirrors and PromiseMirrors are presumably well tested elsewhere.
