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.

3155c994b6 Reintroduce lost idctSparseCol for Alpha. Sorry for adding even more
code duplication, I'm currently working on the put/add variants, but I
did not get them to be as fast as the old method yet...
