Applied with assorted revisions. AFAICT the system column issue is only
a problem for NEW references in BEFORE triggers --- those columns do
read correctly in OLD, and all the time in AFTER triggers. I revised
the parsing logic to enforce that. The patch also missed establishing
dependencies for stuff referenced in the WHEN expression, and there were
a few other minor problems.
