Zig does have its own native x86_64 backend for debug compilation.

They're also getting an aarch64 backend soon (or has it already landed)? Really looking forward to this one for development on my Mac!

My point was that Zig uses their backends (which includes their homegrown ones), but since `zig cc` is a wrapper around Clang, it always goes through the `LLVM` path and sidesteps the Zig backend(s).
