Revision 1.11.2.3 - (view) (download) (annotate) - [select for diffs]

MMXed the calculation of SSE for 8x8 16bit blocks. This helps quite
a lot VHQ=4 mode.

My tests show with trellis:chroma_me:
  - ~20% speed improvement for vhq=4.
  - at least 5% when using vhq=1.

Of course this speedup vanishes if more CPU intensive features are
used. CruNcher who used gmc/qpel, noticed "only" a ~5% speed
improvement.

NB: i'm of course talking about overall speed improvement. Such a
small patch for such a big improvement :-)
