Disable the query flattener optimization for SELECT statements that are on the RHS of vector IN operators. This is a hack that fixes the bug described in ticket [da7841375186386c].

19:01
Enhance the OP_IdxInsert opcode so that it can used unpacked key values if they are available. Update the code generator to take advantage of this new capability. The speedtest1.c test is about 2.6% faster as a result. Later: This also introduced bug [30027b613b]. Bummer. check-in: 925840cf user: drh tags: trunk
18:45
Merge trunk with this branch. Closed-Leaf check-in: dd62d2de user: dan tags: sorter-opt
