  Translator: Make precise-ness a property of AST nodes
  
  Instead of creating a "set of precise nodes", the nodes themselves are
  marked precise.  This change is preparation for another change that
  overhauls precision propagation through the nodes, and which would also
  be storing the promoted precision in the nodes.
