PATCH for lpc_intrin_sse41.c: faster shifts
...0] >> lp_quantization) into: _mm_cvtsi128_si32(_mm_srli_epi64(xmm, lp_quantization)); Encoding of 24-bit .wav files with 32-bit FLAC became noticeably faster. The new code works only if quantization <= 32, but its max value is 15 so the code always work. (max_shiftlimit == (1 << (FLAC__SUBFRAME_LPC_QLP_SHIFT_LEN-1)) - 1 == 15)
