Fix geninterop script and regenerate interop39.cs
- Only record structs when they are defined, not when they are declared - If a struct was only declared when a typedef was created, it won't contain its member declarations. Those have to be drawn from the recorded structs instead. - Rename internal members of AstParser to make it easier to debug
