Removed BackquotedIdent.

In favor of a marker attachment using Attachment, as suggested in
comments. (The Attachment interface needs work.) I did this bit trying
to fix SI-5715, but it's still a bit elusive because the Ident node is
thrown away as soon as there's a member definition.

Also, as far as I can see this will if anything propagate the
backquotedness of an identifier less effectively than before, because
TreeCopiers don't copy attachments. Maybe that's on the "todo" list? The
whole idea seems to depend on their being propagated to copies.
