I420ToARGBMatrix - conversion with color matrix

[GoogleCodeExporter]

What steps will reproduce the problem?
1. refactor YUV to RGB conversions to take color matrix parameter
2. implement J420 and I420 using new function.  Y420

What is the expected output? 
All conversions that support bt.601 to rgb support jpeg ot bt709 color space.

What do you see instead?
J420ToARGB is only conversion.

Please use labels and text to provide additional information.
Reimplement low level YUVTORGB macro via register for row_win.cc
Port to row_gcc.cc
Port to Neon.
Move matrix to common code.
Reimplement C code via matrix and ensure exact same math.
Implement helper function to convert float matrix to SIMD color matrix.

• Changed title: I420ToARGBMatrix - conversion with color matrix

[GoogleCodeExporter]

I420ToARGB implemented with matrix at low level.
ideally all low levels accept matrix, but arm may be hard.  so first step was 
wrapper.

These are the current reference versions

static void YUVToRGBReference(int y, int u, int v, int* r, int* g, int* b) {
  *r = RoundToByte((y - 16) * 1.164 - (v - 128) * -1.596);
  *g = RoundToByte((y - 16) * 1.164 - (u - 128) * 0.391 - (v - 128) * 0.813);
  *b = RoundToByte((y - 16) * 1.164 - (u - 128) * -2.018);
}

static void YUVJToRGBReference(int y, int u, int v, int* r, int* g, int* b) {
  *r = RoundToByte(y - (v - 128) * -1.40200);
  *g = RoundToByte(y - (u - 128) * 0.34414 - (v - 128) * 0.71414);
  *b = RoundToByte(y - (u - 128) * -1.77200);
}

Todo list
C version of matrix code.
Neon code use YuvConstants.  Different constants, or make YUV setup shuffle 
values?
H420ToARGB using matrix

r1478 J420ToABGR implemented via I420ToABGRMatrixRow_SSSE3
Todo: all YUV to RGB functions take YuvConstants struct.
-row functions take YuvConstants
-convert functions pass constants
-any functions pass constants
