15b79d7af8 Experimental changes to improve performance of the OP_MakeRecord opcode, 
and especially the code the writes integer content into the record.
This change is not yet 100% correct.  It is a work in progress.  Parking
on a branch because I need to stop and work on other things.

fec25f94b6 Performance optimization in OP_Column: decode serial types 0 through 6, 8, and 9 (NULL and all integer widths) inline in a switch, avoiding the call and dispatch overhead of sqlite3VdbeSerialGet(). The wide-integer cases 5 and 6 add bulk, but omitting them would leave those types paying the switch miss plus the original call. Other serial types are decoded as before.
