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.

5e4c7ca224 Add attribute that forces alignment of stack to functions that need it. 
Necessary for systems that don't align by default to 16 bytes, required by some
SSE instructions.
Requires GCC >= 4.2.
