Self referenced phi causes assert in falltrough case in RegionNode::Ideal():
assert(dead->outcnt() == 0 && !dead->is_top(), "node must be dead");
The stack looks like:
[3] PhaseIterGVN::remove_dead_node()
[4] PhaseIterGVN::subsume_node()
[5] RegionNode::Ideal()
[6] PhaseIterGVN::transform_old()
[7] PhaseIterGVN::optimize
The ideal case has found a phi with a single input and wants to replace it. The single input is itself!
2644 Phi === 2641 2644
