<pre>
    When initializing a local array, as in 

```c
int a[10] = { 1, 2, 3};
```
the trailing elements must be initialized to zero. clang achieves this goal by first setting the whole array to zero, then adding the individual stores, see https://godbolt.org/z/5x5xP3bsM

We could generate a minimal ``memset`` instead.
