No, there's probably some of them that are only used by gallivm, but not all 
of them. That's something I wanted to do on a follow up to explicitly add all 
llvm components for each driver. But this needs some forensics, to actually 
find out what's really needed ;-)

I'm going to add it to nv30.
swr was calling that function before my changes too. So it probably uses it.
