Hat: speed up cEnter, and remove its NmType argument.
  Because cEnter is called on every reduction step, any improvement in
  its speed should go a long way.  At the moment, it looks like we gain
  only about 1.5% by eliminating tests in C that are no longer useful.
  However, by eliminating its NmType argument, we hope that we can
  change some of the transformation/combinators, to produce much fewer
  NmType nodes in the file.
