Use index hint not honored for AND predicates when CBO is on

This is a fragment of CH2 query 6. This issue is reproducible with similar queries on non-CH2 tables also and happens with both array and non-array indexes.

SELECT count(*) as revenue

FROM   orders o, o.o_orderline ol

WHERE  ol.ol_delivery_d /*+ use-index (orderline_delivery_d) */ >= '2016-01-01 00:00:00.000000'

  AND  ol.ol_delivery_d /*+ use-index (orderline_delivery_d) */ < '2017-01-01 00:00:00.000000';

The hint is honored when there is only a single predicate with no ANDs. The problem happens because the hint is not placed on the AND condition (as it is done for single predicates), but the condition has an "arguments" field which has the annotation. To fix this, we need to check the "arguments" field of the condition for the annotation.
