c4d6d318cf Make DECLARE_ALIGNED_8 align to 8 bytes, never to 16 
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.

d3b60aa685 100l, revision 19728 added a bug that broke twinvq decoding. I forgot to 
multiply the buffer size by the number of channels.

2f17f9c10c 1.5x faster ff_vorbis_floor1_render_list, 5% faster vorbis decoding on Core2. 
1.3x and 3% on G4.
Though I think only part of this speedup is due to my optimizations per se;
some of it is that I got a better roll on the GCC random code generator.
Trivial reorderings of this function have a disproportionate effect on speed.

21c6a0258c Remove useless alignment from MpegEncContext.intra_scantable 
The first member of struct ScanTable is a simple pointer, extra alignment
of which serves no purpose.  The alignment specifier was added along with
some Altivec optimisations also adding a 16-byte-aligned array at the end
of struct ScanTable.  Presumably the redundant, outer alignment was added
by mistake.  The inner one is clearly sufficient.

afe08a728a PPC: remove unnecessary alignment on local variables 
Storing a single element from a vector where all elements have the same
value does not require an aligned destination.  Which element is stored
depends on the alignment of the destination address, but since they all
have the same value, the result is the same regardless of the alignment.
