AVX2 YUV alpha blender and improved unittests

AVX2 version can process 16 pixels at a time for improved memory bandwidth and 
fewer instructions.

unittests improved to test unaligned memory, and test exactness when alpha is 0 
or 255.

GoogleCodeExporter commented 8 years ago 
Support for images with odd height needed.  Code will read past the end of the 
alpha plane.
source/planar_functions.cc:725: for (y = 0; y < height; ++y) {

e.g., if the height is 5, then the chroma channel has height 3.

First loop will use alpha rows 0 + 1,
next loop will use alpha rows 2 + 3
final loop will use alpha rows 4 + 5, but the alpha channel doesn't have a row 
5.

use rounding in scaledown by 2

When scaling down by 2 the formula should round consistently.
(a+b+c+d+2)/4
The C version did but the SSE2 version was doing 2 averages.
avg(avg(a,b),avg(c,d))
This change uses a sum, then rounds.
