invalid function[322]: invalid instruction 0xfe

[mr-tron]

Describe the bug
I tried to instantiate a module https://github.com/ton-community/func-js-bin/raw/main/src/funcfiftlib.wasm and get error invalid instruction 0xfe
To Reproduce

package main

import (
	"context"
	_ "embed"
	"github.com/tetratelabs/wazero"
	"log"
)

//go:embed funcfiftlib.wasm
var wasmBinary []byte

func main() {
	ctx := context.Background()
	r := wazero.NewRuntime(ctx)
	_, err := r.Instantiate(ctx, wasmBinary)
	if err != nil {
		log.Panicln(err)
	}
}

Environment (please complete the relevant information):

• Go version: 1.20.2
• wazero Version: v1.5.1-0.20230925231903-ed8566988007
• Host architecture: amd64

That WASM was likely compiled with threads proposal, which is not finalized (stage 3) and is not supported by wazero.

thank you. I suspected something like this.

Threads and multi-memory were moved to Stage 4 recently: WebAssembly/proposals#176.

I am wondering if there are any plans to implement it? I am trying to use wazero to run whisper transcription and it would help greatly if wazero had threading support.
