Removing the special-case logic in ExecTypeFromTL yields

regression=# SELECT update_pg_pwd();
ERROR:  getTypeOutputInfo: Cache lookup of type 0 failed

which is not exactly pretty, but it beats a core dump.  "SELECT NULL"
still works.

I'm satisfied with this until we get around to breaking up the uses of
"type OID 0" into several pseudo-types with crisper meanings, per
previous discussions.
