Wasm32 v128 Function Params Handling and BTF Relocations Pre-RFC

Recent discussions in the Rust Internals forum highlight two significant technical developments. Firstly, there's a proposal to change how wasm32 handles v128 function parameters, aiming to prevent unnecessary spilling into the shadow stack, which can optimize performance in certain scenarios. Secondly, a pre-RFC on BTF relocations suggests a new approach to improve debugging and introspection capabilities in Rust. These changes could impact how developers write and debug Rust code, especially in performance-critical applications.
