  * Bug-fix for infix function definitions (parse/rename)
    
  Fix a crash provoked by
  
  	x `op` y = x
  	op       = True
  
  The trouble was that there is currently a single 'infix' flag for the
  whole group; and RnTypes.checkPrecMatch was therefore expecting the
  second eqn to have two args.
  
  This fixes the crash, and also or-s the infix flags for the various
  eqns together; previously it was just taken from the first eqn, which
  was wrong.
