Fix broken {xufailed} production that made HEAD fail on

Browse Source 
select u&42 from table-with-a-u-column;
Also fix missing SET_YYLLOC() in the {dolqfailed} production that I suppose
this was based on.  The latter is a pre-existing bug, but the only effect
is to misplace the error cursor by one token, so probably not worth
backpatching.
