                  uninitialized variable used as subscript
      
      Grouping select from a "constant" InnoDB table (a table
      of a single row) joined with other tables caused a crash.

        Bug #44886: SIGSEGV in test_if_skip_sort_order() -
                    uninitialized variable used as subscript
        
        1. The test_if_order_by_key function returned unitialized
           used_key_parts parameter in case of a "constant" InnoDB
           table. Calling function uses this parameter values as
           an array index, thus sometimes it caused a crash.
           The test_if_order_by_key function has been modified
           to set used_key_parts to 0 (no need for ordering).
        
        2. The test_if_skip_sort_order function has been
           modified to accept zero used_key_parts value and
           to prevent an array access by negative index.
