This happens because the orig_decl that we are trying to use in emitting 
the using decl info appears to have been trashed or garbage collected 
before we emit it.

I think i know why.

The ICE was introduced with:
        * decl.c (duplicate_decls): Call ggc_free on declarations we will
        not be needing any longer.

But it looks like reverting it might be papering over the overall problem.

For the log, this is blocking utility/assert_test and 
utility/current_function_test in Boost.

Something is really wrong here.
If we take the following TU:
void abort (void);
namespace std {   using ::abort;  }
void foo()
{
  using std::abort;
  abort();
}

We output a call to std::abort which does not exist at all.  Why are we doing that.
I think this is what is causing us to ICE in the first place.
With 3.4.0 and 3.3.x, we get a call to extern "C" abort which seems right but I think it is wrong still.
