Detailed Description

   Constraints fall into two categories: register constraints
   (define_register_constraint), and others (define_constraint,
   define_memory_constraint, define_address_constraint).  We
   work out automatically which of the various old-style macros
   they correspond to, and produce appropriate code.  They all
   go in the same hash table so we can verify that there are no
   duplicate names.  
   All data from one constraint definition.
