I don't know if this is the best fix for the problem but it does solve a case where we got different codegen with/without debug info present. Originally found for my out of tree target but I think the attached AArch64 testcase exposes the problem as well.

I'm also not sure who can review this. Added @kparzysz since I think you wrote the original code and @foad and @arsenm since I think I've seen you in other reviews of TailDuplicator.
