  Log Message:
  -----------
  Sema: add support for `__attribute__((__swift_newtype__))`

Add the `swift_newtype` attribute which allows a type definition to be
imported into Swift as a new type.  The imported type must be either an
enumerated type (enum) or an object type (struct).

This is based on the work of the original changes in
