This is a long-known limitation of LLVM IR and there are a lot of proposals to fix it.  It would be great if the LLVM Foundation would fund someone to do the work, as it isn’t a sufficiently high priority for any of the large LLVM consumers and would make a huge difference to the utility of LLVM for a lot of people.
