Detailed description

Test Time: 2019/10/24

Test Environment:
  OS: Ubuntu 16.04
  Emscripten: 1.39.0, LLVM upstream backend
  Browser: Chrome, Version 79.0.3941.4 (Official Build) dev (64-bit)
  Hardware: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz with 12 logical cores

In my test, cvtColor with param YUV2BGR made chrome crash with OpenCV.js+simd.
And the same situation came to haar face detector, too.

The same issue comes when applying bilateral filter (cv.bilateralFilter) and perspective transformation (cv.warpPerspective). Chrome crashes with Aw Snap error.

Steps to reproduce

Use bilateral filter:

cv.cvtColor(src, mat, cv.COLOR_RGBA2RGB);
cv.bilateralFilter(mat, dstC3, bilateralDiameter, bilateralSigma, bilateralSigma, cv.BORDER_DEFAULT);

Apply perspective transformation:

let M = cv.getPerspectiveTransform(imgTri, dstTri);
cv.warpPerspective(image, warpedImage, M, new cv.Size(w, h));
