Clean up bogosities in pg_opclass, pg_amop, pg_amproc. There are amproc
entries now for int8 and network hash indexes. int24_ops and int42_ops
are gone. pg_opclass no longer contains multiple entries claiming to be
the default opclass for the same datatype. opr_sanity regress test
extended to catch errors like these in the future.
