If I take a simple SIMD test from emscripten and build with `MEMORY64=2` (lowering) I get errors like this one: ``` $ wasm-opt --memory64-lowering --strip-producers in.wasm -o out.wasm -g --mvp-features...

segfault in wasm-opt

I'm seeing this with quite a lot of wasm64 tests in emscripten: ``` wasm-opt: /usr/local/google/home/sbc/dev/wasm/binaryen/src/wasm.h:715: T *wasm::Expression::cast() [T = wasm::Const]: Assertion `int(_id) == int(T::SpecificId)' failed. emcc: error: '/usr/local/google/home/sbc/dev/wasm/binaryen-out/bin/wasm-opt --memory64-lowering --strip-producers...

This was originally posted as an Emscripten issue ([#13150](https://github.com/emscripten-core/emscripten/issues/13150)) but it really involves a change to Binaryen so I'm reposting it here. An app I'm porting has 3000 instrumented functions...

SIMD types and instructions aren't documented in the JS API

I'm reading https://github.com/WebAssembly/binaryen/wiki/binaryen.js-API and I noticed literally none of the SIMD types available (available in the latest version on npm) are documented. Could this be resolved so I'm not just...

Support Asyncify + Try-Catch [Can't build web-gphoto2 with -fwasm-exceptions instead of -fexceptions]

web-gphoto2 builds with pthreads, Asyncify, exceptions and LTO, and I'm not sure which combo is specifically problematic here, but the end result is that it crashes when trying to switch...
