Subject: More migration to raw_ostream, the water has dried up around the
 iostream hole.  - Some clients which used DOUT have moved to DEBUG. We are
 deprecating the    "magic" DOUT behavior which avoided calling printing
 functions when the    statement was disabled. In addition to being
 unnecessary magic, it had the    downside of leaving code in -Asserts builds,
 and of hiding potentially    unnecessary computations.
