      Bug#12867557: Valgrind: conditional jump/move at key_cmp
      
      This problem may occur when starting a JOIN execution for the second
      and subsequent time, such as when a subquery is evaluated in the
      context of an UPDATE statement to evaluate whether a row qualifies
      to be updated. The problem may also appear only in the case of a
      loosescan semi-join strategy. When the previous execution had
      qualifying rows, the found_match flag may be left with value TRUE,
      so that we erroneously assume that there is a row in loosescan_buf
      that we may compare the current row with.
      
      The problem is fixed by clearing the found_match flag when entering a
      new join_tab level within sub_select().
      
      mysql-test/include/subquery_sj.inc
        Added test case for bug#12867557.

        In sub_select(), added initialization of loosescan match flag when
        entering a new join_tab level.
