b3f0276b9e Fix test cases so that they work with the new EXPLAIN QUERY PLAN output 
format.  Only some of the cases have been fixed.  This is an incremental
check-in.

e28eb64d09 Fix a memory leak in the processing of nested row values. This problem has 
existed every since row values support was added (version 3.15.0, 2016-10-14)
but was only just now detected by OSSFuzz.

4d1c6845ff Fix an incorrect table lookup used to find the appropriate search operator 
for a WHERE clause on a row-value inequality.  The incorrect table lookup
was causing an incorrect answer for the less-than operator.
