Log Message:
-----------
Fix a couple of places in execMain that erroneously assumed that SELECT FOR
UPDATE/SHARE couldn't occur as a subquery in a query with a non-SELECT
top-level operation. Symptoms included outright failure (as in report from
Mark Mielke) and silently neglecting to take the requested row locks.
Back-patch to 8.3, because the visible failure in the INSERT ... SELECT case
is a regression from 8.2. I'm a bit hesitant to back-patch further given the
lack of field complaints.
