Fix broken {xufailed} production that made HEAD fail on
select u&42 from table-with-a-u-column;Also fix missing SET_YYLLOC() in the {dolqfailed} production that I supposethis was based on. The latter is a pre-existing bug, but the only effectis to misplace the error cursor by one token, so probably not worthbackpatching.
