[Eli Friedman via Phabricator via llvm-commits]

> This could only have an impact on explicit uses or clobbers of LR by the inline asm itself, which were already possible prior to this patch, so I believe it won't cause any issues.

It won't cause any "new" issues, in some sense; it's probably feasible to write a testcase without this patch.  But this patch probably makes it easier to trigger.
