The arm64 ABI defines x18 as a platform register, and as such platforms may reserve it for their own purposes. This CL unconditionally removes x18 from the allocatable register list (previously it was only excluded from arm64 Windows). If, for some reason, we want to keep x18 allocatable on some platforms, we can explicitly enable it for specific platforms in the future.
