7e9ffc69ec MDEV-21472: ALTER TABLE ... ANALYZE PARTITION ... with EITS reads and locks all rows 
Do not collect EITS statistics for this statement:

  ALTER TABLE t ANALYZE PARTITION p

EITS stats are currently global, not per-partition.
Collecting global stats when we are asked to process just one partition
causes issues for DBAs.

92e49bb066 MDEV-4360: ANALYZE shows "Table is already up to date" while updating stats 
- Show a line with "Engine-independent statistics collected" when ANALYZE command
  caused EITS statistics to be recollected.

e42024cd0a Fixed bug mdev-3866. 
The invalid implementation of the method Field_bit::cmp_max could
trigger a valgrind complain or could lead to incorrect statistical
data when collecting engine-independent statistics on BIT fields.
