[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

* [GSoC2019]

Fix rebase issue

Building OpenCV.js by Emscripten

Download and install Emscripten.

Execute build_js.py script:

python <opencv_src_dir>/platforms/js/build_js.py <build_dir>

If everything is fine, a few minutes later you will get <build_dir>/bin/opencv.js. You can add this into your web pages.

Find out more build options by -h switch.

For detailed build tutorial, check out <opencv_src_dir>/doc/js_tutorials/js_setup/js_setup/js_setup.markdown.
