Thank you @no1wudi :-)
Do we want to have it as option? You say this tool is experimental so maybe its good to make it optional just in case it produces broken binary? :-)
Does CMake build is in sync with Make build both will have this optimization enabled?

- as far as i know, wasi-sdk doesn't have wasm-opt.
