022d2f886c add SSE2 variants for alpha filtering functions 
The 'inverse' variants are harder to parallelize, since
the result of filtering is used for prediction.
The 'direct' way is relatively easier.

The heavy bottleneck left for optimization is still GradientUnfilter()

a3946b8956 enc_neon: fix building with non-Xcode clang (iOS) 
check for __apple_build_version__ to distinguish the two; a version
check could work as Apple bumped Xcode's to 5.x/6.x, but it's unclear
how upstream will deal with their versioning as they go 3.6+, so avoid
it for now.

Pascal Massimino
bad775715a simplify the Histogram struct, to only store max_value and last_nz 
we don't need to store the whole distribution in order to compute the alpha

Later, we can incorporate the max_value / last_non_zero bookkeeping
in SSE2 directly.

e0c809ad23 Move Entropy methods to lossless.c 
Move all the Entropy evaluation methods to lossless.c (from histogram.c).
There's slight difference in the way entropy is computed for evaluating
entropy in prediction methods and histogram (literal) for huffman trees.
Plan (later) to merge few (static) methods and reduce the code size.

This change has no impact on the compression speed/density.

27bfeee43a QuantizeBlock SSE2 Optimization: 
Another store to load forward block was detected coming from the function
FTransform.
FTransform save the output data 4 times 8 bytes each. when this data is
later being loaded by the QuantizeBlock function in one chunk of 16 bytes
that caused a store to load forward block.
The fix was done in the FTransform function where each two consecutive 8 bytes
were merged into one 16 bytes register and saved into the memory.
This fix gives ~21% function level gain and 1.6% user level gain.

6d6865f0db Added SSE2 variants for Average2/3/4 
The predictors based on Average2 are tad slower.

Following is the performance data for these predictors normalized to
number of instruction cycles (as per valgrind) per operation:
- Predictor6 & Predictor7 now takes 15 instruction cycles compared to 11
  instruction cycles for the C version.
- Predictor8 & Predictor9 now takes 15 instruction cycles compared to 12
  instruction cycles for the C version.

The predictors based on Average4 is faster and Average3 is tad slower:
- Predictor10 (Average4) now takes 23 instruction cycles compared to 25
  instruction cycles for the C version.
- Predictor5 (Average3) now takes 20 instruction cycles compared to 18
  instruction cycles for the C version.

Maybe SSE2 version of Average2 can be improved further. Otherwise, we can
remove the SSE2 version and always fallback to the C version.
