There's a flag in TestMRCompiler (generate = false) and you need to set
it to true to generate new golden files.

Subject: how do you generate golden files?
I have a patch for the alias issue I mentioned on the user list, but
it requires regenerating some of the golden files (merge join
serializes physical operators, which now have a new field "alias", so
the serialized data changed a bit).
I wasn't able to find any instructions regarding how to generate the
plans on the wiki. Help?
