a6c2ed91ca Optimizations to the main loop inside sqlite3VdbeExec() to help VDBE byte code 
run a few percent faster.

8cff69df11 Enhance the OP_Found and OP_NotFound opcodes so that they can accept an 
array of registers as an unpacked record in addition to a record built
using OP_MakeRecord.  Use this to avoid OP_MakeRecord calls during IN
expression processing.
