c4e84b7295 A testcase() macro added to help ensure that the fix to the omit-noop-join 
optimization from yesterday does not regress.

934e796e43 Ensure that the WhereInfo.revMask bitmap is adjusted when tables are removed

[forum:/forum/8a1e467e905b8d27|format post 8a1e467e905b8d27].

c1547d1f7a Do not allow sqlite3_blob_open() to work on a any table that contains 
generated columns, even columns of the table which are not generated themselves,

This restriction could be relaxed some, but that would be a lot of code

the unexpected ordering of characters using the default collation (memcmp()
order) in UTF-16LE, the LIKE/GLOB optimization restricts its attention to
the pattern prefix that is all ASCII, which is the common case.

1521ca4c20 Refactor the SrcItem object so that information about subqueries is stored 
in a separately allocated Subquery object.  This reduces the memory requirements
for SrcItem and makes the code run faster.  It also provides an expansion path
for subquery processing that does not burden simple queries.  The current
checking mostly works, but there are still issues that need to be tracked
down and fixed.
