Description
修复 top k big tensor 问题，由于测试样例过多，因此未对全部失败样例进行测试，对两类错误进行了采样测试：
精度错误：
paddle.topk(Tensor([1, 1, 2281701379],"float32"), 9, axis=-1, largest=False, ) pass
paddle.topk(Tensor([1, 1, 2281701379],"float32"), 13, axis=-1, largest=True, ) pass
cuda700
paddle.topk(x=Tensor([8, 268435457],"float64"), k=4, ) pass
paddle.topk(Tensor([6, 7, 51130564],"float64"), k=2, ) pass
修复 median big tensor 问题：
paddle.median(Tensor([3, 4, 190141782],"int32"), 0, True, ) pass
paddle.median(Tensor([3, 380283564, 2],"int32"), 0, True, )
[paddle error] paddle.median(Tensor([1073741824, 4],"float16"), -1, False, )
unsupported operand type(s) for *: 'Tensor' and 'Tensor'
