Generally you don't want "dead" constant's debug info stripped in a normal compilation because you still want to be able to see these constants in the debugger. In your workflow the compiler has special knowledge that this debug info will be available externally, so it makes sense there.

Is it okay to add an llvm::opt to customize this pass or there are better ways?
