Hi!

On the following testcase we ICE, because fn is __builtin_unreachable
that doesn't have to have a cgraph node created.
The name method on cgraph nodes calls decl_printable_name, so the following
patch does that even if the cgraph node is NULL.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

        (eliminate_dom_walker::before_dom_children): Use
        lang_hooks.decl_printable_name instead of
        cgraph_node::get ()->name ().

OK.
