…eLapkin add a test for combining RPIT with explicit tail calls tracking issue: rust-lang#112788 fixes rust-lang#139305 Combining return position impl trait (RPIT) with guaranteed tail calls does not currently work, but at least it does not ICE any more. Using RPIT probably should work, see also rust-lang#144953. The snippet in the issue is not valid for a variety of reasons, and based on the assert that got triggered the ICE was just any `-> impl Trait` at all, so I've made a minimal example using RPIT. r? `@WaffleLapkin`
