Ganesh Ajjanagadde	5989add4ab	lavu/x86/lls: add fma3 optimizations for update_lls This improves accuracy (very slightly) and speed for processors having fma3. Sample benchmark (fate flac-16-lpc-cholesky, Haswell): old: 5993610 decicycles in ff_lpc_calc_coefs, 64 runs, 0 skips 5951528 decicycles in ff_lpc_calc_coefs, 128 runs, 0 skips new: 5252410 decicycles in ff_lpc_calc_coefs, 64 runs, 0 skips 5232869 decicycles in ff_lpc_calc_coefs, 128 runs, 0 skips Tested with FATE and --disable-fma3, also examined contents of lavu/lls-test.
