Subject: Support expressions of the form 'scalar op ANY (array)' and 'scalar
 op ALL (array)', where the operator is applied between the lefthand scalar
 and each element of the array.  The operator must yield boolean; the result
 of the construct is the OR or AND of the per-element results, respectively.

Original coding by Joe Conway, after an idea of Peter's.  Rewritten
by Tom to keep the implementation strictly separate from subqueries.
