1109b6b888 Enable SSE2 4x4 ADST/DCT transform
This commit enables SSE2 4x4 foward hybrid transform. The runtime
goes from 249 cycles down to 74 cycles. Overall around 2% speed-up
at no compression performance change.

15fefced7d Cleanup inside vp9_decodemv.c.
Adding read_skip_coeff function. Renaming decode_mv to read_mv for
consistency with another function names. Removing redundant function
arguments. Renaming kfread_modes to read_intra_mode_info, read_mb_modes_mv
to read_inter_mode_info, vp9_decode_mb_mode_mv to vp9_read_mode_info,
vp9_decode_mode_mvs_init to vp9_prepare_read_mode_info. Inlining function
mb_mode_mv_init inside vp9_prepare_read_mode_info.

d00b8e5f82 Inline vp9_get_coef_context() (and remove vp9_ prefix).
Makes cost_coeffs() a lot faster:
4x4: 236 -> 181 cycles
8x8: 888 -> 588 cycles
16x16: 3550 -> 2483 cycles
32x32: 17392 -> 12010 cycles

Total encode time of first 50 frames of bus (speed 0) @ 1500kbps goes
from 2min51.6 to 2min43.9, i.e. 4.7% overall speedup.

af660715c0 Make coefficient skip condition an explicit RD choice.
This commit replaces zrun_zbin_boost, a method of biasing non-zero
coefficients following runs of zero-coefficients to be rounded towards
zero, with an explicit skip-block choice in the RD loop.

The logic is basically that if individual coefficients should be rounded
towards zero (from a RD point of view), the trellis/optimize loop should
take care of it. If whole blocks should be zero (from a RD point of
view), a single RD check is much more efficient than a complete
serialization of the quantization loop.

Quality change: derf +0.5% psnr, +1.6% ssim; yt +0.6% psnr, +1.1% ssim.
SIMD for quantize will follow in a separate patch. Results for other
test sets pending.

1374a06bd8 Optimize partition search order
This commit change the partition search order to allow checking of
rectangular partition to be done after square partitions. It also
added a speed feature to skip rectangular partition check when
NONE is better than SPLIT in RD sense.

This feature roughly speed up encoder by 1.5X with loss on compression
-0.91% on cif set
-0.56% on stdhd set

e4d2c255f1 test_libvpx: disable pthreads in gtest for win targets
currently threading is internal to libvpx so thread safety is unneeded
in libgtest -- visual studio builds already operate in this way as they
do not have pthread.h available by default.

this removes an unconditional link to libpthread using $(extralibs)
should libvpx require it.
