1a338fb306 enc_sse41: add Disto4x4 / Disto16x16 
direct translation from sse2; minor gain, fewer instructions

94055503e3 encoding SSE4.1 stub for StoreHistogram + Quantize + SSE_16xN 
Visible speed-up, thanks to pshufb and pabsw and psignw use.

had to tweak configure.ac to make "smmintri.h" presence correctly
detected (we need to set the CPPFLAGS instead of the CFLAGS!)

moving slow, or when we had a quite good first iteration already
(means: the picture is "not difficult")

ef98750027 Speedup method StoreImageToBitMask by 5%. 
Speedup method StoreImageToBitMask by replacing the code to find histogram
index and Huffman tree codes at every iteration to a more optimal code that
updates these only when the current pixel (to write) crosses the histogram
tile-row boundary.

This change speeds up the StoreImageToBitMask method by 5%.

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.
