Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits.
...
While this "wastes" up to 2x32 bytes it makes the code slightly simpler and
less confusing.

initialized by ff_fft_init and using different code can result in slightly

The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively. This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.

The DECLARE_ALIGNED_8 macro is defined to align to 16 bytes instead
the 8 suggested by the name on some CPUs. None of the uses of this
macro ever need 16-byte alignment, cases which once did having been
changed to always specify 16 bytes explicitly.

idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.

Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

Scaling (i)MDCT output has no runtime overhead and can be used to improve
