Review comment:
1. Yes, we will extend this to 'ALL'. And it is easy to implement based on
this PR.
2. I think it has not much relation with this PR. This PR focuses on
subquery which will be rewrote as Join. Like `InSet`, 'ANY' with `array` will
use code generation for computing. They are totally different. And IMO, it's ok
to support.
