r296215, "[PDB] General improvements to Stream library." r296217, "Disable BinaryStreamTest.StreamReaderObject temporarily." r296220, "Re-enable BinaryStreamTest.StreamReaderObject." r296244, "[PDB] Disable some tests that are breaking bots." r296249, "Add static_cast to silence -Wc++11-narrowing." std::errc::no_buffer_space should be used for OS-oriented errors for socket transmission. (Seek discussions around llvm/xray.) I could substitute s/no_buffer_space/others/g, but I revert whole them ATM. Could we define and use LLVM errors there? llvm-svn: 296258
