The other main way we could provide __unix et al would be to add them to
tools/shared.py in Emscripten (see the comment "wasm target does not
automatically define emscripten stuff"). It's not clear to me whether that's
better than adding the macros to clang itself or
sunfish added a comment.
When adding new predefined macros, please also add the new macros to
test/Preprocessor/init.c (and remove negative tests that no longer apply).
Also though, I'd also like to understand this a little more. Even with
emulation, there will be limits to how Unixy a Web

For WebAssembly, I'm expecting we'll switch to emitVoidPtrVAArg and eschew
LLVM's vaarg instruction too, as other targets do. This exposes the expanded
