d9a5dab2da Remove uses of SIGILL for CPU extension detection, that method is not acceptable 
in a library.
Should not change anything for PPC, the autodetection is currently pointless due
to other code being compiled with -maltivec as well (and detection for OSX and
AmigaOS remains in place).
SPARC binaries built with VIS support can now only run on systems with VIS.

465c9fdeeb Remove pointless HAVE_ALTIVEC #ifdefs from a file that only contains AltiVec 
optimizations and no general PPC optimizations. Instead make the file be
compiled conditional to HAVE_ALTIVEC.

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.
