[Bug middle-end/24589] New: [4.1 Regression] wrong code with zero sized structs on CONSTRUCTOR

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Testcase:
   void abort (void);
   int ii;
   typedef struct {} raw_spinlock_t;

   typedef struct {
     raw_spinlock_t raw_lock;
   } spinlock_t;


   raw_spinlock_t one_raw_spinlock (void)
   {
       raw_spinlock_t raw_lock;
       ii++;
       return raw_lock;
   }

   int main(void)
   {
     spinlock_t lock = (spinlock_t) { .raw_lock = one_raw_spinlock() };
     if (ii != 1)
       abort ();
     return 0;
   }
