- Closes apache#19917.

Reduce the number of rows retrieved by pushing down more filters when
possible. Example:

```sql
create table t1 (k int, v int);
create table t2 (k int, v int);

-- k=1 is pushed to t1 and t2
explain select * from t1 left join t2 on t1.k = t2.k where t1.k = 1;

- Added unit tests.

Yes.

No.
