Unused warnings for functions: -static functions -functions in anonymous namespace -class methods in anonymous namespace -class method specializations in anonymous namespace -function specializations in anonymous namespace Unused warnings for variables: -static variables -variables in anonymous namespace -static data members in anonymous namespace -static data members specializations in anonymous namespace Reveals lots of opportunities for dead code removal in llvm codebase that will interest my esteemed colleagues. llvm-svn: 111086
