aarch64: get_cabac inline asm
...
Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets
approximately 20% faster (no cycle counts available) compared to clang
from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall
speedup might be explained by additional inlining of get_cabac().

aarch64: h264 chroma motion compensation NEON optimizations

Since RV40 and VC-1 use almost the same algorithm so optimizations for
those two decoders are easy to do and included.
