The problem was that parts of Simd8x16ShuffleOperand were uninitialized.
Original message:
[wasm] Stop decoding operands after error.
When we decode operands of WebAssembly instructions, we do not use the
current pc but a pc of the instruction plus some offset. However, the
pc of the instruction + offset can become invalid in case of a decoder
error. Therefore we have to stop decoding operands explicitly in case
of an error.
