I have pushed this patch to github in case you want to pull from there: https://github.com/jayfoad/llvm-project/tree/only-copy-live-lanes

There is very high chance this test in unfixable with your changes as these prevent the very situation where the KIILs were formed. I'd say you may just generate checks there. At the end this code snippet did not compile and asserted, so we need to make sure it compiles. Bundles themselves are just an implementation detail.
