bc843d3960 First cut at planner support for bitmap index scans. Lots to do yet, 
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.

cd47a4d3c4 With pg_autovacuum becoming increasingly popular it's important to 
have a working stats collector.  This test is able to discover the
problem that was present in 7.4 Beta 2.
