c00365b46d aarch64: Make the function pointer tables position independent 
This allows running the code on android, where 64 bit binaries with
text relocations aren't allowed to be loaded.

ac6b95dbc0 aarch64: add ',' between assembler macro arguments where missing 
llvm's integrated assembler does not accept spaces as macro argument
delimiter when targeting darwin. Using a explicit delimiter is a good
idea in principle since it makes case like 'macro 4 -2' vs 'macro 4 - 2'
clear.

9aa4592076 aarch64: assembler in clang-3.4 ignores the division by two 
Values are positive powers of two, so just replace it with right shift.

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
point decoder is approximately 7% faster.

0e083d7e43 build: Group general components separate from de/encoders in arch Makefiles 
This is in line with how the top-level libavcodec Makefile is structured.

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().

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