They are currently implicit because TargetMachine::shouldAssumeDSOLocal implies dso_local. For external data, clang -fno-pic emits the dso_local specifier for ELF and non-MinGW COFF. Adding explicit dso_local makes these tests in align with the clang behavior and helps implementing an option to use GOT indirection for external data access in -fno-pic mode (to avoid copy relocations).
