Subject: [PATCH v42] Support updates based on old and new tuple in row
 filters.

When applying row filter on updates, check both old_tuple and new_tuple
to decide how an update needs to be transformed.

UPDATE
old-row (match)       new-row (no match)    -> DELETE
old-row (no match)    new row (match)       -> INSERT
old-row (match)       new row (match)       -> UPDATE
old-row (no match)    new-row (no match)    -> (drop change)

Also tuples that have been deformed will be cached in slots to avoid
multiple deforming of tuples.
