      WL#5860: Windows and Solaris compilers don't like static const
      member variables.

      WL#5559 -  Factor tmp table out of optimizer.
        Part 3: Unify the code for creation of temporary tables
                for GROUP BY/ORDER BY
      Changed JOIN::create_intermediate_table() so that it 
      can be used to create both temporary tables, and let it
      return a pointer to the created table, and use it to also
      create JOIN::exec_tmp_table2.
     @ sql/
        1. Extended JOIN::create_intermediate_table() with parameters
           for characteristics that vary between the two temporary
        2. Changed JOIN::create_intermediate_table() to return the
           pointer to the created temporary table, instead of 
           assigning it to exec_tmp_table1.
        3. Moved code in JOIN::create_intermediate_table() that are
           only relevant to exec_tmp_table1 to JOIN::exec().
        4. Moved code in JOIN::create_intermediate_table() related
           to optimization for distinct to a new private function  
           JOIN::optimize_distinct(). (To be called from
           JOIN::exec() after creating the exec_tmp_table1
           for time being, but longer term this should be moved to
           optimization phase.)
        5. Call create_intermediate_table() to create 
     @ sql/sql_select.h
        Created new private function JOIN::optimize_distinct() to 
        optimize distinct when used on a subset of tables in query.
        Changed signature of JOIN::create_intermediate table to be 
        able to handle creation of both temporary tables used for
