Log Message:
-----------
Fix more problems with rewriter failing to set Query.hasSubLinks when inserting
a SubLink expression into a rule query. We missed cases where the original
query contained a sub-SELECT in a function in FROM, a multi-row VALUES list,
or a RETURNING list. Per bug #4434 from Dean Rasheed and subsequent
investigation.
Back-patch to 8.1; older releases don't have the issue because they didn't
try to be smart about setting hasSubLinks only when needed.
