Add more cross-type comparisons to contrib/btree_gin.
Using the just-added infrastructure, extend btree_gin to support cross-type operators in its other opclasses. All of the cross-type comparison operators supported by the core btree opclasses for these datatypes are now available for btree_gin indexes as well.
