@LFsWang Would you like to do this?

ok

Comment:

according to the binary format of instruction OpCodes, relaxed-simd instructions need 3-byte length of OpCode: 0xFD, 0x01, 0x00 to 0x2F.

As the current WasmEdge structure, we only supports 2-byte OpCode. Refactoring before implement this proposal is necessary.
