Detailed Description

RTL expression ("rtx").   

The GTY "desc" and "tag" options below are a kludge: we need a desc
field for gengtype to recognize that inheritance is occurring,
so that all subclasses are redirected to the traversal hook for the
base class.
However, all of the fields are in the base class, and special-casing
is at work.  Hence we use desc and tag of 0, generating a switch
statement of the form:
  switch (0)
    {
    case 0: // all the work happens here
   }
in order to work with the existing special-casing in gengtype.
