This reverts commit 4725ab7e51.
The constants are necessary to avoid breakage in vs9 builds:
warning C4180: qualifier applied to function type has no meaning; ignored
error C2436: 'f2_' : member function or nested class in constructor initializer list
while compiling class template member function 'std::tr1::tuple<T0,T1,T2,T3,T4,T5,T6,T7,T8,T9>::tuple(const int &,const int &,unsigned int (__cdecl &))'
..\test\variance_test.cc : see reference to class template instantiation 'std::tr1::tuple<T0,T1,T2,T3,T4,T5,T6,T7,T8,T9>' being compiled

The scanning order has the first 12 coefficients of the 8x8 2D-DCT
sitting in the top left 4x4 block. Hence the partial inverse 8x8
2D-DCT allows to handle cases with eob below 12.
The overall runtime of the inverse 8x8 2D-DCT unit is reduced from
166 cycles (using SSE2) to 150 cycles (using SSSE3).

vp9_is_upper_layer_key_frame() definition does not match declaration--
it was missing the second const.

This commit enables ssse3 assembly implementation of the 8x8
inverse 2D-DCT with only first 10 coefficients non-zero. The
average runtime for this unit goes down from 198 cycles to 129
cycles (34.8% faster).

Merged minq tables for arf and gf cases.
These tables were almost the same and for
VBR the arf table was not used at all.

Small adjustment to the active Q range calculations.
These changes should slightly extend the available Q range
for KF/GF/ARF and narrow it for other frames.
The results for this change in isolation are broadly positive
for SSIM and average PSNR and slightly up but mixed for opsnr.
derf +0.293% opsnr, +1.286% SSIM
std-hd + 0.528% opsnr, + 1.746% SSIM
yt +0.056% opsnr, +0.457% SSIM
yt-hd -0.147% opsnr, + 0.226% SSIM

The test vector is produced to have a single key frame, with segment
map enabled and transmitted. Yet no segment feature is active.

Includes changes that are not compatible with VS windows builds.
Amongst other things stdint.h is not supported in VS.

When the variance is far less than sse, the block is considered to
be under light change. All the energy is compacted into DC coeff
and can be coded at low cost. In such situation, switch the rate-
distortion modeling from sse+var based back to variance based.
Note that this is a temporary solution to handle the rare situations
where the scene light changes.
