dee0f09197 C++: Cover variable sized member arrays without a size in Buffer.qll 
Currently the extractor incorrectly emits 0 for the array `data` below:
```
struct myStruct { // c
   ...
   char data[]; // v
};
```
This will change in the future, and  no size will be emitted anymore.
This commit makes sure `Buffer.qll` handles arrays without sizes.

83fdff54c4 Work around missing size for typedef 
See #8805 for the underlying issue. The symptom was bad IR generation on a large number of functions because we never generated an `IRVariable` for a parameter with the affected type.
