Missed -Wconstant-conversion warning in the case of plain C arrays

Consider the following C:
```c
int main(void)
{
signed char foo = 255; // does warn
signed char bar[] = {255}; // does *not* warn
return 0;
}
```
For `foo` we get a `-Wconstant-conversion` warning as expected:
```
warning: implicit conversion from 'int' to 'signed char' changes value from 255 to -1 [-Wconstant-conversion]
3 | signed char foo = 255; // does warn
| ~~~ ^~~
```
But for `bar` we get no warning, which is a shame.
This is similar to https://github.com/llvm/llvm-project/issues/35534.
