86d0ea7558 Use an OP_NotFound opcode to cancel futile IN operators early. The current 
implementation is suboptimal because it always runs teh OP_NotFound.  This
still needs to be enhanced to only do the OP_NotFound if no results have been
seen on the current loop.

a0368d9396 Demonstration code on a possible technique for optimizing the use of IN 
operator on columns to the right of multicolumn indexes.  If the OP_Noop
generated where were really a new opcode that checked to see if there existed
any entries in the index with a matching prefix, it might prevent unnecessary
iterations of the IN operator.
