And, unfortunately, fixing this problem for Clang in the obvious way then breaks my GCC 4.8.2 build:

/src/llvm/lib/Target/Hexagon/HexagonGenPredicate.cpp: In member function ‘{anonymous}::Register {anonymous}::HexagonGenPredicate::getPredRegFor(const {anonymous}::Register&)’:
/src/llvm/lib/Target/Hexagon/HexagonGenPredicate.cpp:233:36: error: no match for ‘operator<<’ (operand types are ‘llvm::raw_ostream’ and ‘{anonymous}::PrintRegister’)
   DEBUG(dbgs() << __func__ << ": " << PrintRegister(Reg, *TRI));

Just FYI.
