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.

642364a48b Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the 
need for separate boolean registers to record when a co-routine has finished.

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.

e08ecad58a Do not mark the ephemeral tables used to hold the RHS of IN clauses as 
unordered because the NGQP will use those ephemeral tables to help order the
output.  This is not an issue for standard SQLite since ephemeral tables
there are always ordered, regardless of the hint.  It only affects systems
that substitute an alternative storage engine.
