This is a slightly invasive change in the engine, hence I was not planning
to backport.
Also, I realized after this PR that self-joins mostly actually work except
in few corner cases which I accidentally hit. And even if you hit them and
get the error in the JIRA, for most of them, you can add projects in your
code to get around them.
