37ccfcfeb9 New test-control that returns the number of calls to 
sqlite3BtreeMovetoUnpacked() on the main database and then resets the
counter.  This only works for SQLITE_DEBUG builds.

58d6f633ba Reduce the N in the logN term for the sorting cost associated with computing 
DISTINCT by B-Tree by half, under the assumption that the DISTINCT will
eliminate about half the rows of output.  This is really a wild guess.  But
we do not have any better way of estimating what the row-count reduction due
to DISTINCT will actually be.

861889e4f8 When doing an UPDATE or DELETE using a multi-column index where only a few 
of the earlier columns of the index are useful for the index lookup,
postpone doing the main table seek until after all WHERE clause constraints
have been evaluated, in case those constraints can be covered by unused
later terms of the index, thus avoiding unnecessary main table seeks.

68c0c71065 For UPDATE and DELETE, use OP_DeferredSeek always. If the seek must later 
be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have
been processed.  This obviates the need for the WHERE_SEEK_TABLE and
WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing
complication, and it allows the covering index optimization to be used
further into WHERE clause processing.
