Add the OPFLAG_MULTICOLUMN flag to the OP_Column opcode. Rearrange OP_Column instructions to take advantage of the new flag for a small performance increase (Leaf check-in: 5e5d6e8680 user: drh tags: faster-OP_Column)

Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. (check-in: 7fb1626866 user: drh tags: trunk)
