This adds assembly parsing support for the new EH (exnref) proposal. `try_table` parsing is a little tricky because catch clause lists use `()` and the multivalue block return types also use `()`. This handles all combinations below: - No return type (void) + no catch list - No return type (void) + catch list - Single return type + no catch list - Single return type + catch list - Multivalue return type + no catch list - Multivalue return type + catch list This does not include AsmTypeCheck support yet. That's the reason why this adds a new test file and use `--no-type-check` in the command line. After the type checker is added as a follow-up, I plan to merge https://github.com/llvm/llvm-project/blob/main/llvm/test/MC/WebAssembly/eh-assembly-legacy.s with this file. (Turning on `-mattr=+exception-handling` adds support for all legacy and new EH instructions in the assembly. `-wasm-enable-exnref` in `llc` only controls which instructions to generate and it doesn't affect `llvm-mc` and assembly parsing.)
