Sunny Bains 61c2b12da7 Fix bug# 18274 InnoDB auto_increment field reset on OPTIMIZE TABLE
OPTIMIZE TABLE recreates the whole table. That is why the counter gets reset.
Making the next autoinc column persistent is a separate issue from resetting
the value after an OPTIMIZE TABLE. We already have a check for ALTER TABLE
and CREATE INDEX to preserve the value on table recreate. We should be able to
add an additional check for OPTIMIZE TABLE to preserve the next value.
