I had to add the phase to subnode's virtual sub() declaration because
CmpPNode::sub passes NULL to things expecting a phase. I've attached
what is working for me, and it makes one allocation scalar replacable.
Additionally, with the "do escape analysis after an initial
IterGVN.optimize pass," it's able to scalar replace another similar
situation.
