Add a basic TargetARM32 skeleton which knows nothing.

ARM32?  (though that messes with line length...)

Yeah that is why I left out the 32. I could say "ARM32 machine instructions".

Changed that for now (and the x86 one too...), but can change back if you prefer
Low-level.

That looks good, thanks!
