      With the introduction of AutoGetDb::ensureDbExists() and AutoGetCollection::ensureDbExists() in SERVER-45955, there is no longer a need for AutoGetOrCreateDb and removing it would simplify the codebase. Going through and directly translating the uses should be trivial, however anywhere we use this pattern:

      AutoGetOrCreateDb autoDb(opCtx, ns.db(), MODE_IX);
      Lock::CollectionLock collLock(opCtx, ns, MODE_IX);
      Database* db = autoDb.getDb();
      

      should be changed into

      AutoGetCollection autoColl(opCtx, ns, MODE_IX);
      Database* db = autoColl.ensureDbExists();
      

      This change leads to implicitly creating the system.views collection hitting this uassert, which we would should investigate whether we can circumvent.
