** an unchanging column during an UPDATE operation, then the P5
** value is 1.  Otherwise, P5 is 0.  The P5 value is returned
** by sqlite3_vtab_nochange() routine and can be used
** by virtual table implementations to return special "no-change"
** marks which can be more efficient, depending on the virtual table.
** value is OPFLAG_NOCHNG.  This will cause the sqlite3_vtab_nochange()
** function to return true inside the xColumn method of the virtual
** table implementation.  The P5 column might also contain other
** bits (OPFLAG_LENGTHARG or OPFLAG_TYPEOFARG) but those bits are
** unused by OP_VColumn.
