495b64be2b nak: Make Dst its own type 
Instead of having Src::src_ref and Dst share a type, make them separate
enums.  We're not really getting any benefit from them being the same
enum type anymore and this means we avoid things like immediates in
destinations.  We can't make the type system do all our work for us but
this seems tractable.

While we're reworking things we also implement From<> for stuff instead
of having quite as many new_*() constructor variants.
