      Added a test case for bug #12095.
    sql_class.h:
      Fixed bug #12095: a join query with GROUP_CONCAT over a single row table.
      Added a flag to the TMP_TABLE_PARAM class forcing to put constant
      items generated after elimination of a single row table into temp table
      in some cases (e.g. when GROUP_CONCAT is calculated over a single row
      table).

      Fixed bug #12095: a join query with GROUP_CONCAT over a single row table.
      If GROUP_CONCAT is calculated we always put its argument into a temp
      table, even when the argument is a constant item.
    sql_select.cc:
      Fixed bug #12095: a join query with GROUP_CONCAT over one row table.
      If temp table is used to calculate GROUP_CONCAT the argument should
      be always put into this table, even when it is a constant item.
