        Revert the fix of Bug#38996 Race condition in ANALYZE TABLE
        
        This is branches/zip@r6032 in SVN and _is part_ of
        revid:svn-v4:16c675df-0fcb-4bc9-8058-dcc011a37293:branches/zip:6113
        in BZR.
        
        This is being reverted because now the code is serialized directly on
        index->stat_n_diff_key_vals[] as the fix for
        Bug#53046 dict_update_statistics_low can still be run concurrently on same table
        goes.

        Protect dict_index_t::stat_n_diff_key_vals[] with an array of
        mutexes.
        
        Testing: tested all code paths under UNIV_SYNC_DEBUG
        for the one in dict_print() one has to enable the InnoDB table monitor:
        CREATE TABLE innodb_table_monitor (a int) ENGINE=INNODB;
