portable intrinsics / wasm (WebAssembly). integrating this into the
webp_js path will be left until the implementation is more complete.

f209a5481e Use the plane code and not the distance when computing statistics. 
As backward references use the plane code when checking the cost
of a distance, statistics used to compute the cost should use it too.
This provides a small compression improvement at no speed cost.
