Fix omission of OCLASS_TRANSFORM in object_classes[]

This was forgotten incac7658 (and its fixupad89a5d). Since itseems way too easy to miss this, this commit also introduces a mechanismto enforce that the array is consistent with the enum.Problem reported independently by Robert Haas and Jaimin Pan.Patches proposed by Jaimin Pan, Jim Nasby, Michael Paquier and myself,though I didn't use any of these and instead went with a cleanerapproach suggested by Tom Lane.Backpatch to 9.5.Discussion:https://www.postgresql.org/message-id/CA+Tgmoa6SgDaxW_n_7SEhwBAc=mniYga+obUj5fmw4rU9_mLvA@mail.gmail.com https://www.postgresql.org/message-id/29788.1437411581@sss.pgh.pa.us
