the primary user of this will probably end up being find-first-set-bit/find-
last-set-bit, which i'll get around to...

966cdfb600 Implement READPORT/WRITEPORT, implementing the last X86 regression tests 
that were failing with the pattern selector.  Note that the support that
existed in the simple selector was clearly broken in several ways though
(which has also been fixed).
