Change Target & Process so they can really be initialized with an invalid architecture. 
Arrange that this then gets properly set on attach, or when a "file" is set.
Add a completer for "process attach -n".

Caveats: there isn't currently a way to handle multiple processes with the same name.  That
will have to wait on a way to pass annotations along with the completion strings.
