    Description

      Call devirtualization happens only during parsing.
      If devirtualization fails, virtual call is issued and it stays the same irrespective of receiver type changes (later optimization passes can improve the type so devirtualization becomes possible).
      With the introduction of post-parse inlining, it becomes possible to inline through virtual calls as well if there's enough type information available.
