      Bug#14672885 SHOULD NOT PRUNE AUTO PARTITIONED TABLES
       - Skip pruning if table is in an auto partitioned engine
       - Refuse explicit partitions for auto partitioned engines

      Bug#14649493 ASSERTION FAILURE IN __GCOV_FLUSH IN _DB_SUICIDE_ (DBUG_SUICIDE)
      
      Grab THR_LOCK_gcov before calling __gcov_flush()
      to avoid multiple parallel calls.
     @ mysys/stacktrace.c
        Remove the ifdef HAVE_gcov code (note the lowercase)
        We never define that macro anymore,
        and the flushing of gcov data is now done in _db_suicide_ anyways.
