You mean `alloca` as in the C function, not as in the LLVM concept, I guess.

And yes, this is all very brittle code, having to potentially call these functions upon each register change. I wonder if there's a better way, like making the concept of FrameBase be a flag on a register, such that when the register gets deleted it is automatic. But that would probably still require special purpose when renumbered, when lowered to a local, etc etc.
