Downloaded tarball for kernel release 5.5.4, and I cannot compile
tools/testing/selftests/bpf/ with latest LLVM release version 9.

And has llvm 9 always worked here?  

Yes, llvm-9 used to work for tools/testing/selftests/bpf/.  

As of when?

Kernel v5.4 works when compiling BPF-selftests with LLVM 9.0.1.
