80ff38130e dsp/alpha*.c: rework WEBP_USE_<arch> ifdef 
add a dummy init rather than repeating the '#ifdef WEBP_USE_...'
pattern.

602a00f93f fix iOS arm64 build with Xcode 6.3 
the standard vtbl functions are available there [1][2].
based on a patch from: aaroncrespo
fixes issue #243.

[1]
http://adcdownload.apple.com//Developer_Tools/Xcode_6.3_beta/Xcode_6.3_beta_Release_Notes.pdf
[2] Apple LLVM Compiler Version 6.1
- Xcode 6.3 updates the Apple LLVM compiler to version 6.1.0.
[...]
Support for the arm64 architecture has been significantly revised to
align with ARM's implementation, where the most visible impact is that a
few of the vector intrinsics have changed to match ARM's specifications.

2382050748 1-2% faster encoding by removing an indirection in GetResidualCost() 
The MIPS code for cost is not updated yet, that's why i keep Residual::*cost
around for now. Should be removed in favor of *costs later.

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()
