where the DWARF is in the .o files so they can track down the actual type for a forward declaration. This was working before for just DWARF files, but not for DWARF in .o files where the actual definition was in another .o file. Modified the main thread name in the driver to be more consistent with the other LLDB thread names. llvm-svn: 118383
