    Optimize creation of language specs

    * Various simple optimizations for creation of specs. Mostly
      additional caching of non-growing data related to the
      structure of the language spec classes. For huge workflows
      with thousands of tasks these changes reduce execution time
      by dozens of seconds.
    * Minor style changes.
