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.

14bd2a9f25 replace brute force find_optimal_param() with a closed-form solution. 
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.
