[Bug target/38988] New: Cannot build crtstuff.c with -mcmodel=large -fPIC -O2

[sje at cup dot hp dot com]

If you compile the following code (cut down from crtstuff.c) with
-mcmodel=large -fPIC -O2 on a 64 bit x86 target GCC will ICE.  There are at
least two problems, one in cselib_hash_rtx, and if that is fixed then I get a
shared rtx abort.

The test case is 

        typedef long unsigned int size_t;
        typedef void (*func_ptr) (void);
        static func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) };
        static void __attribute__((used)) __do_global_dtors_aux (void)
        {
          extern func_ptr __DTOR_END__[];
          size_t dtor_idx = 0;
          const size_t max_idx = __DTOR_END__ - __DTOR_LIST__ - 1;
          func_ptr f;
          while (dtor_idx < max_idx)
          {
            f = __DTOR_LIST__[++dtor_idx];
            f ();
          }
        }
