  * Eliminate spurious warnings in hat-trans.
    * Previously, the IdentMap (that maps a constructor, field, or method
      to its type or class) was only used on entities defined in this module.
      This led to spurious warnings about some identifiers that were imported
      and re-exported.
    * Now, the IdentMap is always paired up with the AuxTree (mapping
      from Identifier to AuxInfo) to form an 'Environment', so the
      two are always carried together.  Thus, getImports extends the
      IdentMap as well as the AuxTree.  Also, when relabeling the abstract
      syntax tree, we now have correct information about the kind (Var,
      Con, Field, Method) of each entity, rather than a poor approximation.
