Add more cross-type comparisons to contrib/btree_gin.

Browse Source 
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.
