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.

083310dfcc Change the weighting of binary searches on tables to 1/10th the cost of a 
search on an index.  Change the assumed reduction in search space from a
indexed range constraint from 1/3rd to 1/4th.  Do not let the estimated 
number of rows drop below 1.

5e377d90ed If the outer loop of a join must be a full table scan, make sure that an 
incomplete ANALYZE does not trick the planner into use a table that might
be indexable in an inner loop.  Ticket [13f033c865f878]
