   * This an array of "struct type *"'s with one pointer per DNTT index.
   * Given a DNTT index, we look in this array to see if we have
   * already processed this DNTT and if it is a type definition.
   * If so, then we can locate a pointer to the already-built
   * "struct type", and not build it again.
   * 
   * The need for this arises because our DNTT-walking code wanders
   * around. In particular, it will encounter the same type multiple
   * times (once for each object of that type). We don't want to 
   * built multiple "struct type"'s for the same thing.
   *
   * Having said this, I should point out that this type-vector is
   * an expensive way to keep track of this. If most DNTT entries are 
   * 3 words, the type-vector will be 1/3 the size of the DNTT itself.
   * Alternative solutions:
   * - Keep a compressed or hashed table. Less memory, but more expensive
   *   to search and update.
   * - (Suggested by JB): Overwrite the DNTT entry itself
   *   with the info. Create a new type code "ALREADY_BUILT", and modify
   *   the DNTT to have that type code and point to the already-built entry.

 *   Routine description:
 *     There are a variety of places when scanning the DNTT when we
 *     need to interpret a "type" field. The simplest and most basic 
 *     example is when we're processing the symbol table record
 *     for a data symbol (a SVAR or DVAR record). That has
 *     a "type" field specifying the type of the data symbol. That
 *     "type" field is either an "immediate" type specification (for the
 *     fundamental types) or a DNTT pointer (for more complicated types). 
 *     For the more complicated types, we may or may not have already
 *     processed the pointed-to type. (Multiple data symbols can of course
 *     share the same type).
 *     The job of hpread_type_lookup() is to process this "type" field.
 *     Most of the real work is done in subroutines. Here we interpret
 *     the immediate flag. If not immediate, chase the DNTT pointer to
 *     find our way to the SOM record describing the type, switch on
 *     the SOM kind, and then call an appropriate subroutine depending
 *     on what kind of type we are constructing. (e.g., an array type,
 *     a struct/class type, etc).
