Michael Gottesman f73276259e [loop-rotate] In OSSA, instead of creating address phis, sneak the address through the phi using a RawPointer. ...

In OSSA, we do not allow for address phis, but in certain cases the logic of
LoopRotate really wants them. To work around this issue, I added some code in
this PR to loop rotate that as a post-pass fixes up any address phis by
inserting address <-> raw pointer adapters and changing the address phi to
instead be of raw pointer type.
