4fd7c82e6a SSE2 variants of Subtract-Green: Rectify loop condition 
When 4 pixels are left, they should be processed with SSE2.

Decoding is marginally faster (~0.4%).
Encoding speed: No observable difference.

51f406a5d7 lossless_sse2: relocate VP8LDspInitSSE2 proto 
this is in line with the other dsp files and silences a build warning.

0f4f721b12 separate SSE2 lossless functions into its own file 
expose the predictor array as function pointers instead
of each individual sub-function

+ merged Average2() into ClampedAddSubtractHalf directly
+ unified the signature as "VP8LProcessBlueAndRedFunc"

no speed diff observed
