This reverts commit r368849, because it breaks some bots (e.g. llvm-clang-x86_64-win-fast). It turns out this is not as NFC as we had hoped, because operator== will consider two std::error_codes to be distinct even though they both hold "success" values if they have different categories. llvm-svn: 368854
