Bug fixes

Description

43 paddle.diag
修改infermeta，符号推导，如果size < 0, size = 0
修改kernel，如果out numel为0，Alloc后返回

PaddleAPITest测试通过

131 paddle.masked_fill
Job2 87 paddle.Tensor.masked_fill
输出维度是x,mask维度broadcast后的维度
反向填充0

torch测试填充为0

import torch
x=torch.randn([2,1,3])
x.requires_grad=True
y=torch.randn([2,0,3]).type(torch.bool)
v=torch.tensor(1.0)
v.requires_grad=True
out=torch.masked_fill(x, y, v)
out.sum().backward()
print(x.grad)
print(v.grad)

tensor([[[0., 0., 0.]],

        [[0., 0., 0.]]])
tensor(0.)

PaddleAPITest测试通过
