For panic=unwind on Wasm targets, define __cpp_exception tag Since llvm/llvm-project 159143, llvm no longer weak links the __cpp_exception tag into each object that uses it. They are now defined in compiler-rt. Rust doesn't seem to get them from compiler-rt so llvm decides they need to be imported. This adds them to libunwind.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
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).
