This patch creates skeleton implementation for the DWARFLinkerParallel. It also integrates DWARFLinkerParallel into dsymutil and llvm-dwarfutil, so that empty DWARFLinker::link() can be called. To do this new command line option is added "--linker apple/llvm". Additionally it changes existing DWARFLinker interfaces/implementations to be compatible: use Error for error reporting for the DWARFStreamer, make DWARFFile to owner of referenced resources, other small refactorings.
