- In ha_innobase::prepare_inplace_alter_table(), InnoDB should check whether the table is empty. If the table is empty then server should avoid downgrading the MDL after prepare phase. It is more like instant alter, does change only in dicationary and metadata. - Changed few debug test case to make non-empty DDL table
