fill_rectangle() calls to operate on 32-bit words instead of 64-bit ones.

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.

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.
