  branches/5.1: Fix Bug#38187 Error 153 when creating savepoints
  InnoDB previously treated savepoints as a stack e.g.,
    SAVEPOINT a;
    SAVEPOINT b;
    SAVEPOINT c;
    SAVEPOINT b; <- This would delete b and c.

  This fix changes the behavior to:
    SAVEPOINT a;
    SAVEPOINT b;
    SAVEPOINT c;
    SAVEPOINT b; <- Does not delete savepoint c

  branches/5.1: dict_load_table(): If dict_load_indexes() fails,
  invoke dict_table_remove_from_cache() instead of dict_mem_table_free(),
  so that the data dictionary will not point to freed data.
