Bug#27006: AFTER UPDATE triggers not fired with INSERT ... ON DUPLICATE KEY

Browse Source 
UPDATE if the row wasn't actually changed.

This bug was caused by fix for bug#19978. It causes AFTER UPDATE triggers
not firing if a row wasn't actually changed by the update part of the
INSERT .. ON DUPLICATE KEY UPDATE.

Now triggers are always fired if a row is touched by the INSERT ... ON
DUPLICATE KEY UPDATE.
