Rollup merge of #132077 - alexcrichton:wide-arithmetic, r=jieyouxu

Add a new `wide-arithmetic` feature for WebAssembly

This commit adds a new rustc target feature named `wide-arithmetic` for WebAssembly targets. This corresponds to the [wide-arithmetic] proposal for WebAssembly which adds new instructions catered towards accelerating integer arithmetic larger than 64-bits. This proposal to WebAssembly is not standard yet so this new feature is flagged as an unstable target feature. Additionally Rust's LLVM version doesn't support this new feature yet since support will first be added in LLVM 20, so the feature filtering logic for LLVM is updated to handle this.

I'll also note that I'm not currently planning to add wasm-specific intrinsics to `std::arch::wasm32` at this time. The currently proposed instructions are all accessible through `i128` or `u128`-based operations which Rust already supports, so intrinsic shouldn't be necessary to get access to these new instructions.

Website | Getting started | Learn | Documentation | Contributing

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 integrate 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).
