          Wail did a little research and a very small localized change can flip the hash join operator's input traversal order and thus address this issue!  I think we should do it.  We will have to replace existing results with new results for tests anyway, once we add the build/probe info into the plans, so - let's do it, yes?  (If need be we can add an optional flag used in tests that prints out plans the old way so that we could defer the expected results issue.)
