Ok, this gave the right error on my system, when I ran it individually:

error: using the autodiff feature requires setting `lto="fat"` in your Cargo.toml

error: aborting due to 1 previous error

I probably didn't notice it between all the other failures.

rustc().input("test.rs").arg("-Zautodiff=Enable").arg("-Clto=fat").emit("llvm-ir").run();
llvm_filecheck().patterns("array.check").stdin_buf(rfs::read("test.ll")).run();
}
