Codegen: View Shadows Array in NestedSDFG

I have a strange error, after some experiments I have concluded the following:
- There is a nested SDFG that has a transient of name, e.g. "X".
- In the parent SDFG there is a view that has the same name, i.e. "X"

In that case the code generator will generate for the nested SDFG:
```c++
X = new float[N];
```
without declaring `X`, i.e. the line `float* X`, that should precede the allocation, is missing.

Currently I have only a big SDFG that has this pattern.
The error vanishes, once I rename the view in the top level SDFG or turn it into an array.
I added the SDFG and scripts that shows I "fixed" the error.

I will also try to come up with a smaller example.
