This passed CI a couple times previously, so even though the lanes aren't working right now, is it fine to merge it? |

Right now on main we spend a good chunk of cpu time just calling _emscripten_get_now in order to measure how long interpreter code generation takes. On most targets the equivalent timestamp checks are fast but on wasm, they're not.
So this PR disables those checks in wasm release builds specifically. Based on my measurements this should improve startup time a little bit.
