These are routines supposed to be in libgcc. I don't know if it's an
obligation. But I can't hurt I guess. I thought __clzhi2 also caused the
other "Too much Ram used" bug. Maybe that was __clzsi2?
I have made a implementation for __clzsi2/hi/qi. Did not test them however.
But it seems that testing has just become real easy :D. Will look into it
tomorrow at the office.

Thanks for all the effort!
