radeonsi: Navi family support requires LLVM 9 or higher
I've got an RX 5700XT running with AMDGPU kernel driver and Mesa 19.2.0 on the host. OpenGL applications work fine and successfully use this GPU.
If I uninstall org.freedesktop.Platform.GL32.default, it starts unpacking steam runtimes and whatnot, but once it's done it throws an glXChooseVisual error (which is expected, as I understand). So I assume the GL32 runtime extension isn't built against LLVM 9.
Acceptance Criteria
Steam (or other 32 bit application) can be run with Navi 10 GPUs.
