54a51d3840 lavc/flacenc: partially unroll loop in flac_enc_lpc_16 
It now does 12 samples per iteration, up from 4.

From 1.8 to 3.2 times faster again.  3.6 to 5.7 times faster overall.
Runtime is reduced by a further 2 to 18%.  Overall runtime reduced by
4 to 50%.

Same conditions as before apply.

0081a14e7d lavc/flacenc: add sse4 version of the 16-bit lpc encoder 
From 1.8 to 2.4 times faster.  Runtime is reduced by 2 to 39%.  The
speed-up generally increases with compression_level.

This lpc encoder is not used with levels < 3 so it provides no speed-up
in these cases.

Conflicts:

This split is somewhat restructured leaving the xvid IDCT available
outside mpeg4 if manually selected.

The code also could not be merged unchanged as it conflicted with a
bugfix in FFmpeg
