3956a5e0ea aarch64: NEON vorbis_inverse_coupling 
From the ARMv7 NEON version. 16 times faster as the C version, overall
more than 12% faster vorbis decoding on Apple's A7.

8f9fe6ae34 aarch64: NEON fixed/floating point MPADSP apply_window 
30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating

dfe224f377 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().
