I just realized this was designed in purpose https://github.com/llvm/llvm-project/commit/d8a423cd71bb2a9b7666fd58fc82db16b4666d1d, though I don't know the motivation to keep it SSA, I'll abandon this patch first.

> nice conceptual abstraction that code we add only defines each virtual register once

I agree with it. But in other way, we can still `assert(!MRI->isSSA())` here and define virtual registers more than once.
