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.

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.

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.
