Certainly pieces are still there.  For example, we still create two
insn streams, one for tailcalls one for normal calls.  I don't think
we attach them to CALL_PLACEHOLDERS anymore.

My only concern was the possibility that there may be some
dependencies between the code you're zapping and the remaining
multiple stream expansion stuff we do in calls.c.  If after reviewing
calls.c you don't expect any problems, then go ahead with your 
original cleanup of CALL_PLACEHOLDER and we'll deal with whatever
cleanups we can do in calls.c separately.

ps.  I hope this isn't a duplicate -- I've had some outgoing email
trouble lately.
