What is the expected behavior?

It should be a gray scale image

What do you see instead?

white

What version are you using? 
VP9 Encoder v1.2.0-3844-g7b50333

On what operating system?
Windows

Can you reproduce using the vpxdec or vpxenc tools? What command line are
you using?

Please provide any additional information below.

vpxenc -w 854 -h 480 --fps=30/1 --target-bitrate=200 
graytone.854x480_30Hz_P420.yuv -o graytone0.tmp.vp9.webm --fpf=graytone_vp9.fpf

tried aug 18 build

The encoder thinks it worked
Pass 2/2 frame  150/150     3208B     171b/f    5132b/s 2104582 us (71.27 fps)

But vpxdec repros the issue as well:
vpxdec --codec=vp9 --limit=10000 --i420 graytone0.vp9.webm -o 
graytone_vp9.webm.854x480_30Hz_P420.yuv

1 pass also fails
vpxenc/dec were built like this:

CROSS=x86_64-w64-mingw32- ../libvpx/configure --target=x86_64-win64-gcc 
--enable-static-msvcrt --disable-install-docs --disable-unit-tests 
--disable-docs
make -i V=1

Seems this is readily reproducible at speed 0/1/2 on linux as well: 
v1.2.0-4091-g1c159c4.

After some bisecting the ssse3 version of vp9_quantize_b_32x32 is at least 
partially to blame.
