don't need their number in a comment either.

There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.

it doesn't leave the underlying stream in unbuffered mode when
the stream was originally buffered.

Also, change WriteAsOperand back to plain raw_ostream. This
lets it work for either formatted_raw_ostream or plain
raw_ostream, so that it doesn't have to force a buffer flush
on a plain raw_ostream.
