  * Tidy up the treatment of SPECIALISE pragmas
  
  Remove the now-redundant "const-dicts" field in SpecPrag
  
  In dsBinds, abstract over constant dictionaries in the RULE.
  This avoids the creation of a redundant, duplicate, rule later
  in the Specialise pass, which was happening before.
  
  There should be no effect on performance either way, just less
  duplicated code, and the compiler gets a little simpler.
