[ydl-gen] IBM XLC/C++ and XLF for YDL on Cell

[Warren Nagourney]

Rob,

When IBM supported the Mac, I also did a comparison and found that xlc  
and xlf were from 20% to a factor of 2 faster than gcc and g77 (on a  
G5). More recently, when IBM released free versions of these products  
for the Cell, I did a comparison and found very little difference for  
both the ppu and spu versions. Things might have changed a bit since  
they started charging, but I wouldn't expect big changes. In any case,  
I can't afford the commercial products, so it is moot.
