| Summary |
`-Wextra` demotes `-Winitializer-overrides` from error to warning even when `-pedantic-errors` is present

```cpp
struct A
{
int a;
};
A a{
.a = 10,
.a = 20,
};
```
This correctly errors with `-std=c++20 -pedantic-errors`:
```console
<source>:8:10: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
8 | .a = 20,
| ^~
<source>:7:10: note: previous initialization is here
7 | .a = 10,
| ^~
```
But if I use `-std=c++20 -pedantic-errors -Wextra`, this instead becomes a warning:
```console
<source>:8:10: warning: initializer overrides prior initialization of this subobject [-Winitializer-overrides]
8 | .a = 20,
| ^~
<source>:7:10: note: previous initialization is here
7 | .a = 10,
| ^~
```
I get the same warning if I use just `-std=c++20`.
The correct behavior is for this to be an error if `-pedantic-errors` is present, regardless of `-Wextra`.
