Fix jit/pass/peephole.cpp fuse addmm (#26357)
Summary:
Fix https://github.com/pytorch/pytorch/issues/26328. Reversing the order of inserting nodes. Previously the IR graph looks like
```
graph(%0 : Float(3, 3)):
%5 : Float(3, 3) = aten::addmm(%0, %0, %0, %6, %6)
%6 : int = prim::Constant[value=1]()
return (%5)
```
where %6 is used before created. Now
```
graph(%0 : Float(3, 3)):
%5 : int = prim::Constant[value=1]()
%6 : Float(3, 3) = aten::addmm(%0, %0, %0, %5, %5)
return (%6)
```
