9a4444778f Add the ability to use indices for the first few terms of an ORDER BY clause, 
then sort in batches to handle the later terms.

8e1ee88c88 Change the names of SRT_DistTable and SRT_Table used by CTE to more 
meaningful SRT_DistFifo and SRT_Fifo, respectively.  Simplify the
IgnorableOrderby() macro in the process.

f9f1bdb0c8 Merge trunk fixes for "x IN (?)" handling.

fbb24d1092 The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is 
incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS.  This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.

3d77dee935 Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite 
of SQLITE_NULLEQ and SQLITE_JUMPIFNULL.  This flag indicates that NULL operands
are not possible and raises and assert() if NULL operands are seen.
Also omit an unnecessary scan of the sqlite_sequence table when writing
into an AUTOINCREMENT table.
