gflags has a build warning in the chromium version.
../../third_party/gflags/src/gflags.cc:281:53: error: unused typedef 'true_false_equal' [-Werror,-Wunused-local-typedef]
COMPILE_ASSERT(sizeof(kTrue) == sizeof(kFalse), true_false_equal);

1 error generated.
[8/231] CXX obj/chromium/src/testing/gtest/src/gtest.gtest.o
Its been reported and fixed upstream
https://github.com/gflags/gflags/issues/125
But not pulled into chromium. Last update to flags was in 2013.
This change disables the warning.

Remove inaccurate specializations for 1/4 and 3/4, since they round
incorrectly. Specialize for 100% and 50% are kept due to performance.
Make C and ARM code match SSSE3.
Make unittests expect zero difference.

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.

Some functions run out of registers when compiled for debug,
fpic, with stack frames on 32 bit x86 with clang.
Previously they were enabled based on _DEBUG but that macro
is not set in some build systems. This CL adds DEBUG macro as
well to cover those environments.

previously the I411 format used movd to read U, V pixels.
But this reads 4 bytes, and can cause a memory exception.
pinsrw can be used, but fails on drmemory 1.5, and is slow.
So in this change a movzxw is used to read 2 bytes into EBX,
then copy to xmm0 with movd.
Slightly slower, but no memory exception
Was LibYUVConvertTest.I411ToARGB_Opt (577 ms)
Now LibYUVConvertTest.I411ToARGB_Opt (608 ms)
