We have been using the default names for global symbols to this point. This change introduces proper name mangling for functions. This requires introducing a CXXABI class in the CIRGenModule. Because only target independent name mangling is handled in this patch, the CXXABI class does not require a target-specific implementation. The general mechanism for selecting an implementation is introduced here, but the actual target-specific subclasses are deferred until needed.
