drh aceb31b120 Change the OP_Trace opcode to OP_Init and give it the ability to jump to the
initialization code at the bottom of the program, thus avoiding the need for
an extra OP_Goto.

drh a5750cfe01 Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register
in the result register range as the flag to indicate EOF on an INSERT from
a SELECT, rather than allocating a separate boolean register for that task.

drh 28935364ef If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the
sqlite3BtreeCursorHint() interface to provide hints to the storage engine
about rows that need not be returned.  Hints can be disabled using
SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000).  Cursor
hints are not used by the built-in storage engine of SQLite but might
be useful to applications that provide their own storage engine.  The
current code is work-in-progrss and contains bugs.

drh 0b9dadacd8 Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add
