This code doesn't compile anymore:

ConstantRange Bounds = VR->get(V);
DOUT << "Bounds: " << Bounds;

I think the problem is that DOUT is not a raw_ostream.
I've commented out that code for now.

The plan is to convert everything over to raw_ostream. Sorry, we won't be adding new operator<<'s for std::ostream unless needed in mainline.

Converting DOUT from Support/Debug.h to raw_ostream is fine with me.

Can I just convert llvm:getErrorOutputStream to return errs() instead of cerr?
What is the equivalent of cnoout with raw_ostream?
