Here, valid_initializer_constant_p returns true -- but output_constant aborts,
saying:

      /* Make sure eliminating the conversion is really a no-op, except with    
         VIEW_CONVERT_EXPRs to allow for wild Ada unchecked conversions and     
         union types to allow for Ada unchecked unions.  */
      if (type_size > op_size
          && TREE_CODE (exp) != VIEW_CONVERT_EXPR
          && TREE_CODE (TREE_TYPE (exp)) != UNION_TYPE)
        internal_error ("no-op convert from %wd to %wd bytes in initializer",
                        op_size, type_size);

I don't understand the assertion, given that removing it seems to generate
correct output for this test case.  Since you edited this code not to long ago,
do you have thoughts?
