Describe the bug

Error print when executing the following wat file.

Steps to reproduce

The wat file is :

(module
  (func (result i64)
      v128.const i64x2 -1 1
      global.get 0
      f64x2.replace_lane 0
      i64x2.extract_lane 1
  )

  (global f64 (f64.const 1))
  (export "func1" (func 0)))

The python file is :

import os

from wasmer import engine, wat2wasm, Store, Module, Instance
# from wasmer_compiler_cranelift import Compiler
# from wasmer_compiler_llvm import Compiler
from wasmer_compiler_singlepass import Compiler

engine = engine.Universal(Compiler)

# Create a store, that holds the engine.
store = Store(engine)

# Let's compile the Wasm module with the Cranelift compiler.
__dir__ = os.path.dirname(os.path.realpath(__file__))
module = Module(Store(), open(__dir__ + '/../tmp.wasm', 'rb').read())

# Let's instantiate the Wasm module.
instance = Instance(module)

# Let's call the `sum` exported function.
func1 = instance.exports.func1
results = func1()

print(results)

Execute:

wat2wasm tmp.wat
python tmp.py
