  * Introduced trusted and suspected variant of application combinators.
  
  The suspected application combinators ap and rap always create a trace node for an application.
  The trusted application combinators tap and trap create a trace node for an application, if the function is suspected (no need to trust parent).
  
  Changed transformation to use the new application combinators.
  
  Trace file unchanged.
  Traced code 5-10% faster on small heaps, unchanged for large heaps.
