b12bf03275 aac sbr: align struct member by 32 byte. 
Required because it's used in a call to imdct_half(), which is an AVX
function.

9b9df1cdff h264: new assembly version of get_cabac for x86_64 with PIC 
This adds a hand-optimized assembly version for get_cabac much like the
existing one, but it works if the table offsets are RIP-relative.
Compared to the non-RIP-relative version this adds 2 lea instructions
and it needs one extra register. get_cabac() gets about 40% faster, for
an overall speedup of about 5%.

14e9ffc1e4 h264: use one table instead of several for cabac functions 
The reason is this is easier for PIC code (in particular on darwin...).
Keep the old names as pointers (static in cabac_functions.h so gcc
knows these are just immediate offsets) so the c code can nicely stay the same
(alternatively could use offsets directly in the functions needing the
tables). This should produce the same code as before with non-pic and better
code (confirmed) with pic.

The assembly uses the new table but still won't work for PIC case.
