DO NOT MERGE: QUICKSTEP-121: Added the self-join support.
This PR added the self-join support by assigning the join side info,
instead of relying on the relation id.
Note that now `NestedLoopsJoin` has to use the same term as `HashJoin`
w.r.t. join side. In the other words, the left side is the `probe`, while the
right is the `build`. Also, the join result pair is in the format of
`<build-tid, probe-tid>`.
