[PATCH] Fix 70199

[Richard Henderson <rth at redhat dot com>]

The problem here is that

  void* labels[] = {
    &&l0, &&l1, &&l2
  };

gets gimplified to

  labels = *.LC0;

but .LC0 is not in the set of local decls, so that when copy_forbidden is 
called during sra versioning we fail to forbid the copy.  We could set a 
different flag, but I think it's easiest to just add the artificial decl to 
where it can be seen.

Ok?
