Don't print the entire declaration of the alliassee when `->toChars()` is
called on an `AliasDeclaration`; just printing the name will do. This fixes
#305, which otherwise tries to generate
{{{
  class E {
      void A() {
          alias /* recurse into E->toCBuffer() */ m;
      }
  }
}}}
by way of an infinite recursion (causing a segfault when the stack runs out).
