I update two tuples, so I manually CatalogOpenIndexes() and
CatalogIndexInsert() two times, as per comments in
CatalogUpdateIndexes().

I also removed a couple of useless CommandCounterIncrement(), some
useless definitions in src/include/commands/cluster.h and useless
includes in src/backend/commands/cluster.c.  This version passes the
regression test I had made for previous versions.
