If I build with VS without "--enable-realtime-only" then only one test fails 
(regardless of VPX_SIMD_CAPS=0):

..\test\fdct8x8_test.cc(56): error: Value of: bias_acceptable
  Actual: false
Expected: true
Error: 8x8 FDCT has a sign bias > 1% for input range [-255, 255] at index 36
..\test\fdct8x8_test.cc(56): error: Value of: bias_acceptable

[  FAILED  ] VP9Fdct8x8Test.SignBiasCheck (552 ms)

This should get addressed here:

https://gerrit.chromium.org/gerrit/#/c/47405/

It's worth noting that this problem was reproducible with mingw-w64 and seems 
to have to do with RAND_MAX=32767 in those builds vs. 2^31-1. The current code 
extracts the [0, 255] range from bits 8-16, so there was likely less entropy 
there.
