Detailed Description

Constraints fall into two categories: register constraints
(define_register_constraint), and others (define_constraint,
define_memory_constraint, define_special_memory_constraint,
define_relaxed_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.
