Help with SIMD for emscripten

[Former user]

Hi,

following is rather a question or guidance for how to compile x265 with emscripten with SIMD support.

Considering the current state of emscripten SIMD support, is there anything to be done in order to enable "faster encoding" other than adding -msimd128 flag at compile time? If so, whats the good material to look into?
