Don't these `removeDebugIntrinsicDeclarations` calls (in both files) want to be guarded by `if (UseNewDbgInfoFormat)`?

I don't think it hugely matters if we're about to remove that flag too... but it looks like with your patch we unconditionally remove the intrinsic declarations, even if the intrinsic mode is selected?
