> Define ValidTxnList before starting query optimization

>
> Consider a set of tables used by a materialized view where inserts happened
> after the materialization was created. To compute incremental view
> maintenance, we need to be able to filter only new rows from those base
> tables. That can be done by inserting a filter operator with condition e.g.
> {{ROW\_\_ID.transactionId < highwatermark and ROW\_\_ID.transactionId NOT
> IN(<open txns>)}} on top of the MVs query definition and triggering the
> rewriting (which should in turn produce a partial rewriting). However, to do
> that, we need to have a value for {{ValidTxnList}} during query compilation
> so we know the snapshot that we are querying.
> This patch aims to generate {{ValidTxnList}} before query optimization. There
> should not be any visible changes for end user.
