bors 2c8c85df04 Auto merge of #154999 - cuviper:beta-next, r=cuviper
[beta] reverts and backports

This reverts two `dbg!` changes to avoid regressions[^1][^2] in the upcoming 1.95 release:

- std: avoid tearing `dbg!` prints rust-lang/rust#149869
- don't drop arguments' temporaries in `dbg!` rust-lang/rust#154074
  - ... which was previously backported in rust-lang/rust#154725

This also reverts a stabilization over a late issue[^3] of semantics:

- Stabilize `assert_matches` rust-lang/rust#137487

And a few other backport/reverts from `main`:

- Revert performing basic const checks in typeck on stable rust-lang/rust#154930 / rust-lang/rust#155033
- Revert "`-Znext-solver` Remove the forced ambiguity hack from search graph" rust-lang/rust#154712
- Clarify that core::range ranges do not have special syntax rust-lang/rust#155002

Clippy is backporting 2 ICE fixes and 1 perf regression (via rust-lang/rust#155051):

- https://github.com/rust-lang/rust-clippy/pull/16685 already backported in https://github.com/rust-lang/rust/pull/154211 to stable. This makes sure that it doesn't regress again in beta/next stable
- https://github.com/rust-lang/rust-clippy/pull/16659 The ICE that is being fixed here was introduced in the 1.95 release cycle
- https://github.com/rust-lang/rust-clippy/pull/16652 Perf regression introduced in the 1.95 release cycle.

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).
