e5c3b3f554 Simplify the texture evaluation Disto4x4() 
We don't need to use the exact forward transform,
since it's only a rough evaluation.
-> Removed some shifts and rounding constants.

35bfd4c08f add SSE2 version of Sum of Square error for 16x16, 16x8 and 8x8 case 
+ replace mm_set1_ps(0) by _mm_setzero_si128()

5725cabac0 new segmentation algorithm 
fixes the 'blocky sky problem' (saturation problem: when luma was flat,
chroma noise was taking over, resulting in random segment id assigned.
When just using a common uniform segment was better).

+ side clean-up and readibility/experimentability MACRO'ization
+ added '-map 7' option

7c6e60f4bd make *InitSSE2() functions be empty on non-SSE2 platform 
this avoids the '*.o has no symbols' warning messages

80256b8567 enc_sse2 add missing stdlib.h include 
lost in fbd82b5; most platforms were getting it indirectly through
emmintrin.h.

f06817aaea simplify checks for enabling SSE2 code 
also fixes build issues under vs11 which has a native arm compiler for
windows 8 targets

e06ac0887f create a separate libwebpdsp under src/dsp 
Gathers all DSP-related function (and SSE2 implementations).
Clean-up some unwanted symbolic dependencies so that webp_encode,
webp_decode and webp_dsp are truly independent libraries.

+ opportunistic clean-up:
  * remove unneeded VP8DspInitTables(), now integrated in VP8DspInit()
  * make consistent use of VP8GetCPUInfo() in the various DspInit() funcs
  * change OUT macro to DST
