Subject: Make synthesized sub-register indexes available in the target
 namespace.

TableGen sometimes synthesizes missing sub-register indexes. Emit these
indexes as enumerators in the target namespace along with the
user-defined ones.

Also take this opportunity to stop creating new Record objects for
synthetic indexes.
