8b313a4787 Move Alpha optimized IDCT to own file. Based on a patch by Måns 
Rullgård <mru@users.sourceforge.net>.

I've left out the idctCol2 part, because W4 has recently been decreed
to be 16383, and also I doubt it will give a noticeable speedup.

6c38306600 Make compilable again after DCT cleanup. It gives wrong results, 
though, so I disabled it for now. Anybody knows offhand what might be
the reason?

494e409255 Assembly version of put_pixels. This is currently the function that 
takes the most time, and it allows for more efficient unaligned access
and better control over memory latencies.
