drh cb0540f94a Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial ...

iteration. Keep the cursor open for subsequent runs. This was suppose to be a
performance enhancement, but it is difficult to come up with a query where
is makes a significant difference.  Hence, the change is getting parked
in a branch.
