I tried this in https://github.com/llvm/llvm-project/pull/140300 but it seems
to me that adding this node introduces a lot of complexity for no real gain. I
don't think we track provenance at the MIR level, so having the dedicated node
probably doesn't enable much optimization over G_PTRTOINT+G_TRUNC?
