      Bug#12773464 - 61925: WRONG RESULT WITH AGGREGATE + 
                     NOT BETWEEN + KEY
      
      The problem: opt_sum_query() was invoked to replace MAX(a) with
      a constant in the query:
         SELECT MAX(a) FROM t1 WHERE a NOT BETWEEN 3 AND 9;
      
      However, opt_sum_query() mistook NOT BETWEEN for a BETWEEN
      and therefore found the highest values lower than or equal to 9
      and then tested the predicate on this value. The predicate 
      obviously evaluated to false and MAX(a) therefore evaluated to
      NULL.
      
      opt_sum_query() can only handle conjunctions ("AND" predicates)
      but "x NOT BETWEEN a AND b" is equivalent to "x < a OR x > b" 
      and is therefore not a conjunction. The fix is to return
      from the function without doing const replacement for 
      NOT BETWEENs.

        Add test for Bug#12773464
     @ sql/opt_sum.cc
        opt_sum_query() can only handle conjunctions, so const 
        substitution cannot happen when there is a NOT BETWEEN predicate
