Regression test for issue 42574. Cc #42574. I'm not going to say this *closes* that issue yet, for two reasons: 1. I am still confused about some aspects of the behavior we are observing that bug 2. The "fix" to the diagnostic relies on full NLL (`#![feature(nll)]`); migration mode still has a subpar diagnostic.
