interface to the query planner. The UPDATE implementation adds an
OP_FinishSeek before running the final OP_Insert if one is needed.

of expressions used in an index-on-expression directly from the index rather
than recomputing the value. If the expression has a top-level COLLATE or
unlikely() operator, be sure to clear the corresponding flags prior to
converting it into a TK_COLUMN expression. Failure to do this is most likely
harmless in production, but might cause an assertion fault in debugging builds.

of its table is used by an UPDATE statement in one-pass mode, then avoid the
use of OP_DeferredSeek since the seek might not be resolved prior to the
OP_Delete and OP_Insert that implement the UPDATE.

The WHERE clause of the partial index might not be true if the table of
the partial index is the right table of a left join. So disable the
optimization in that case. Ticket [623eff57e76d45f6]

index lookups for large numbers so that it matches the precision of
ordinary comparison operators. Ticket [40812aea1fde9594]

bottom of the loop to be coded with a single OP_IfNotZero opcode, rather
than a sequence of OP_If, OP_Integer, OP_Goto.

keep the number of parser codes below 256 in order to save parser table space.
But we have long since blown through that ceiling so the addopcodes.tcl script
was just needless complexity. There is no longer any reason to keep it around.

identical terms in the WHERE clause of the query.
