flac dev - Jul 2014 - [PATCH] SSE optimizations

This patch adds new function
FLAC__lpc_compute_residual_from_qlp_coefficients_intrin_sse41()

and rewrites function
FLAC__lpc_compute_residual_from_qlp_coefficients_16_intrin_sse2()

The tests show noticeable speed increase on Intel Core i3/5/7 (up to 30% for -8
mode),
AMD Athlon64, Phenom, Bulldozer/Piledriver, but no increase or even very small
speed decrease (~2% for -8 mode) on Intel Core2.
