The previous commit conflicts with the just-merged pr #131583

Yeah, I clicked the wrong button which took me to a different diff 😆

Compatibility Notes

• [Enable by default the LSX target feature for LoongArch Linux targets] (rust-lang/rust#132140)
• The unstable -Zprofile flag ("gcov-style" coverage instrumentation) has been removed. This does not affect the stable flags for coverage instrumentation (-Cinstrument-coverage) and profile-guided optimization (-Cprofile-generate, -Cprofile-use), which are unrelated and remain available.
• Support for the target named wasm32-wasi has been removed as the target is now named wasm32-wasip1. This completes the [transition] (rust-lang/compiler-team#607) plan for this target following [the introduction of wasm32-wasip1] (rust-lang/rust#120468) in Rust 1.78. Compiler warnings on [use of wasm32-wasi] (rust-lang/rust#126662) introduced in Rust 1.81 are now gone as well as the target is removed.
• [The syntax &pin (mut|const) T is now parsed as a type which in theory could affect macro expansion results in some edge cases] (rust-lang/rust#130635 (comment))
• [Legacy syntax for calling std::arch functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).] (rust-lang/rust#130443 (comment))
• The wasm32-unknown-emscripten target's binary release of the standard library is now [built with the latest emsdk 3.1.68] (rust-lang/rust#131533), which fixes an ABI-incompatibility with Emscripten >= 3.1.42. If you are locally using a version of emsdk with an incompatible ABI (e.g. before 3.1.42 or a future one), you should build your code with -Zbuild-std to ensure that std uses the correct ABI.
• [Declaring functions with a calling convention not supported on the current target now triggers a hard error] (rust-lang/rust#129935)
• [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues] (rust-lang/rust#130654)
