in a library.
Should not change anything for PPC, the autodetection is currently pointless due
to other code being compiled with -maltivec as well (and detection for OSX and
AmigaOS remains in place).
SPARC binaries built with VIS support can now only run on systems with VIS.

compiled conditional to HAVE_ALTIVEC.

3x faster decode_subframe_fixed().
overall flac decoding: 10% faster if file was encoded with fixed predictors.

1.5x faster encode_residual_fixed().
overall flac encoding: 3% faster at compression_levels 0-2.
Originally committed as revision 10625 to svn://svn.ffmpeg.org/ffmpeg/trunk
4x faster order 2, 3.5x order 3, 3x order 4.
overall flac encoding: 35% faster at compression_levels 0-2, no effect at higher levels.

4x faster than c (somehow, even though doubles only allow 2x simd).
overal flac encoding: 15-50% faster on core2, 4-11% on k8, 3-13% on p4.
Originally committed as revision 10621 to svn://svn.ffmpeg.org/ffmpeg/trunk
overall flac encoding: 4-15% faster.
output is not identical to the previous algorithm due to occasional rounding
errors, but the differece is less than .0005% bitrate.
Originally committed as revision 10612 to svn://svn.ffmpeg.org/ffmpeg/trunk
overall flac encoding: 15-50% faster on core2, 8-30% on k8, 2-20% on p4 (depending on compression_level)
