Diego Biurrun	465c9fdeeb	Remove pointless HAVE_ALTIVEC #ifdefs from a file that only contains AltiVec optimizations and no general PPC optimizations.

Loren Merritt	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.
