The first patch adds SSE4.1/SSE4.2 detection. The second patch removes union data in struct FLAC__CPUInfo and replaces it with #ifdefs. Reason: currently it's possible to set or get data.ia32.sse3 value from x86-64 code, etc. It's a potential source of errors (at least that's true for me).
(the 2nd patch requires the 1st to be applied)
