8210233c7b Revise tests cases to align with the new EXPLAIN QUERY PLAN output.

56c65c92cb When the sqlite_stat1 data is missing for some indexes of a table but is 
present for the table itself or for other indexes in the same table, then do
not let the estimated number of rows in that table get too small, as
doing so can deceive the query planner into ignoring a perfectly good index.

175b8f06f7 Remove support for STAT3. The sqlite_stat3 tables are ignored, if they 
exist.  STAT4 continues to work as it always has, and as it is a superset of
STAT3 is the recommended replacement.

8ac02a94ab Update the sqlite3ExprCompare() routine so that it does not think "? IS NOT TRUE" is the same as "? IS TRUE". Fix for [d3e7f2ba5b3].

664d6d139e Fix the NOT NULL logic in the theorem prover that determines when a partial 
index can be used.  Ticket [5c6955204c392ae763a95].

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.

0829169f1e When determining whether or not a partial index is usable, do not assume that the cursor number assigned to each table in the query is the same as its index in the FROM clause. Fix for ticket [98d973b8f5].

f9c8ce3ced Standardize the error messages generated by constraint failures to a format 
of "$TYPE constraint failed: $DETAIL".  This involves many changes to the
expected output of test cases.

d269461c91 Add the index7.test script for testing partial indices with WITHOUT ROWID 
tables.  Fix bugs in ANALYZE located by that script.
