6810b93a81 sse2 version of compute_autocorr(). 
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.

ce611a27be Change rounding of the horizontal DWT to match the vertical one. 
This allows some simplifications and optimizations and should
not have any effect on quality.
