update statements
Only SELECT statements report any examined rows in the slow
log. Slow UPDATE, DELETE and INSERT statements report 0 rows
examined, unless the statement has a condition including a
SELECT substatement.
This patch adds counting of examined rows for the UPDATE and
DELETE statements. An INSERT ... VALUES statement will still
not report any rows as examined.
