x86_64-unknown-none: Expand TargetOptions to specify more details

Browse source 
Specify the `cpu` and the `max_atomic_width` (64).

Set `stack_probes` similarly to other targets to work around known
issues, and copy the corresponding comment from those targets.

Build position-independent code that doesn't require relocations.

(Work on this target sponsored by Profian.)
