On a side track. Not knowing too much regarding simd, what would be the 
best benchmarks to get a comparison of Qt WebAssembly simd support vs. 
non simd (default)? 10 or 15

Particularly looking for speed ups or slow downs, as some wasm simd is 
native opcode provided by the browsers and others are emulated by 
emscripten.
