THIR patterns: Explicitly distinguish `&pin` from plain `&`/`&mut` Currently, `thir::PatKind::Deref` is used for ordinary `&`/`&mut` patterns, and also for `&pin const` and `&pin mut` patterns under `feature(pin_ergonomics)`. The only way to distinguish between them is by inspecting the `Ty` attached to the pattern node. That's non-obvious, making it easy to miss, and is also a bit confusing to read when it does occur. This PR therefore adds an explicit `pin: hir::Pinnedness` field to `thir::PatKind::Deref`, to explicitly distinguish pin-deref nodes from ordinary builtin-deref nodes. (I'm not deeply familiar with the future of pin-patterns, so I'm not sure whether that information is best carried as a field or as a separate `PatKind`, but I think this approach is at least an improvement over the status quo.) r?

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).
