Fix bugs in pg_upgrade_support functions, for GPDB 5 -> GPDB 5 ugprade.

These patches were written by Daniel Gustafsson, I just squashed and
rebased them.

* Add missing 5.0 object procedure declarations

Commit 7ec83119 implemented support for 5.0 objects in
binary upgrade, but missed adding the procedure declarations to
pg_upgrade due to a mismerge.

* Fix opclass Oid preassignment function

The function was erroneously pulling the wrong argument for the
namespace Oid resulting in failed Oid lookups during synchronization.

* Add support functions for pg_amop tuples
