4a7af92cc8 sbrdsp: Unroll and use integer operations
This patch can be controversial, by assuming floats are IEEE-754 and
particular behaviour of the FPU will get in the way.
Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference).

sbr_qmf_pre_shuffle_c: 115 to 76

7c00e9d8ae x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents
The function requires increasing the fuzz factor for the ac3/eac3 encode
tests and even so makes fate fail. It only provides a slight encoding
speedup for legacy CPUs that do not support SS2. Thus its benefit is not
worth the trouble it creates and fixing it would be a waste of time.

94660c3524 threads: always call thread_finish_setup for intra codecs
Intra codecs do not need an update_thread_context() function and never
call ff_thread_finish_setup(). They rely on ff_thread_get_buffer()
calling it. So call it even if the get_buffer2 function pointer is
avcodec_default_get_buffer2 and it has not been called before.

eba1ff3130 atrac3: avoid oversized shifting in decode_bytes()
When `off' is 0, `0x537F6103 << 32' in the following expression invokes
undefined behavior, the result of which is not necessarily 0.

    (0x537F6103 >> (off * 8)) | (0x537F6103 << (32 - (off * 8)))

Avoid oversized shifting.

b164d66e35 ape: make version-dependent decoding functions called via pointers
This will help in supporting old versions, e.g. version 3.93 uses the same
range coder but different predictor and version 3.82 uses different range
coder and predictor. Also this should not make decoding newer versions slower
by introducing additional checks on versions.
