Rollup merge of #148846 - folkertdev:tail-call-rpit, r=WaffleLapkin

add a test for combining RPIT with explicit tail calls

tracking issue: https://github.com/rust-lang/rust/issues/112788
fixes https://github.com/rust-lang/rust/issues/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 https://github.com/rust-lang/rust/issues/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.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
