      First cut at planner support for bitmap index scans. Lots to do yet, · bc843d39

      but the code is basically working.  Along the way, rewrite the entire
      approach to processing OR index conditions, and make it work in join
      cases for the first time ever.  orindxpath.c is now basically obsolete,
      but I left it in for the time being to allow easy comparison testing
      against the old implementation.
