06280ee582 Fix a harmless shadowed-variable warning.

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.

05a86c5c0f Enhance the code generator for INSERT INTO ... SELECT so that the SELECT 
generates output directly in the registers that INSERT INTO will be using,
in many cases, and OP_SCopy operations can thus be avoided.
