@jmorse One other thing I noticed was that `copySalvageSSA` calls `TII.isCopyInstr` whereas livdebugvalues calls `TII->isCopyLikeInstr`

This change in livedebugvalues was made with https://github.com/llvm/llvm-project/pull/74682#issuecomment-1850268782%5C

Should we change the code in `copySalvageSSA` as well?
