f67a10cd0c Define mm_flags/support to be 0 on architectures where they don't exist. 
Make sure we don't try to set them if that's the case.
This lets dct-test and fft-test build with --disable-mmx on x86, but not yet on ARM.

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.
