...
Since there's separate SSE2 implementations of xvid_idct_put/add, this
patch has no practical impact on performance.

x86: xvid_idct: port SSE2 iDCT to yasm
...
The main difference consists in renaming properly labels, and
letting yasm select the gprs for skipping 1D transforms.

...
This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

idct: Split off Xvid IDCT
...
The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.
