planner: stream agg should not be pushed to double read ( #12443 )
...
For the following two reason, we should not push stream agg down to double read
- The aggregate will lost the handle information
- There's no sort operator. The second read is ordered with pk, not by index.

plan: derive col is not null from col op col conditions ( #8603 )
...
Check whether the `op` condition is null rejected, if yes, derive
`col is not null` for both sides of inner join, and for inner side
of outer join.
Also, remove duplicate conditions before pushing them down. Check
if the condition is mutable before removing duplicates.
For AntiSemiJoin, AntiLeftOuterSemiJoin and LeftOuterSemiJoin, do
not generate new `is not null` conditions.

But the `unique key information` is not, obviously.
