raw_os_ostream is definitely linked into Debug/lib/libLLVMSupport.a in  
my LLVM build. (Confirmed with otool.) I'm using the 2.7 release  
branch from a couple weeks ago.

Just for kicks, I added some code to my pass that creates a  
circular_raw_ostream object, and it runs without errors. I wonder  
what's different about raw_os_ostream... Any other possibilities?
