This revision is now accepted and ready to land.

OK as is, but please consider re-using `llvm::sys::path` to distinguish separators.

Please also check that there are no regressions in the clang VFS tests.



================
Comment at: clang/lib/Lex/PPDirectives.cpp:2118
+        return c == '/' || (BackslashIsSeparator && c == '\\');
+      };

----------------
Can you re-use `llvm::sys::path::is_separator` instead of inventing a new thing?  You can explicitly pass `llvm::path::Style::windows` if the Microsoft extensions are enabled.  Otherwise let it default to llvm::path::Style::native.
