I don't really see this as a likely risk, call me back once they have their own unique compiler targets that can't be targeted with LLVM. But even if they did evolve their own unique CPU architecture, that seems like a remarkably low-risk problem compared to the inertia you inevitably acquire using any platform API whatsoever. If you rely on anything beyond bare VM provisioning from any cloud provider you will experience huge pain to move anywhere else. If you are concerned about it, deploy on m6g instances, and put the money you save in a piggybank to pay a consultant to move you when AWS crosses your line.
