DESCRIPTION:

There is HA_EXTRA_WRITE_CAN_REPLACE hint that tells the engine that the
following ::write_row() calls are part of the REPLACE statement, not INSERT.
With this knowledge the engine can execute the replace internally, deleting the
conflicting row in the ::write_row() method instead of returning an error.

We need a similar HA_EXTRA_WRITE_CAN_IGNORE hint to allow engines to optimize
INSERT IGNORE in a similar way.
