    [GSoC 2019] Improve the performance of JavaScript version of OpenCV (OpenCV.js)
    
    * [GSoC 2019]
    
    Improve the performance of JavaScript version of OpenCV (OpenCV.js):
    1. Create the base of OpenCV.js performance test:
         This perf test is based on benchmark.js(https://benchmarkjs.com). And first add `cvtColor`, `Resize`, `Threshold` into it.
    2. Optimize the OpenCV.js performance by WASM threads:
         This optimization is based on Web Worker API and SharedArrayBuffer, so it can be only used in browser.
    3. Optimize the OpenCV.js performance by WASM SIMD:
         Add WASM SIMD backend for OpenCV Universal Intrinsics. It's experimental as WASM SIMD is still in development.
    
    * [GSoC2019] 
    
    1. use short license header
    2. fix documentation node issue
    3. remove the unused `hasSIMD128()` api
    
    * [GSoC2019]
    
    1. fix emscripten define
    2. use fallback function for f16
