This is a tracking issue for psi support. Robust predication support is going to be needed to handle the peculiarities of Minecraft/SBBM.

To get there, we need:

[ ] Add Psi Instruction #9
[ ] Add PsiElimination pass (at first, as an SBBM-only pass) #10
[ ] Write a new if-conversion pass that runs before register allocation and uses psi instructions to perform predication. #11
