Previously a functions debuggable field was set to false in the async transformation (and because it wasn't done yet, not in async* and sync* transformation, though it should have been). Now instead, set the original async status and set debuggable on the c++ side equivalently. Also, on the c++ side, set a functions modifier to async etc if they were originally async etc. BUG= R=asgerf@google.com, kmillikin@google.com, kustermann@google.com Review-Url: https://codereview.chromium.org/2697193008 .
