In #70480 the `-fexperimental-bounds-safety` flag was added.
Currently Clang will emit a warning that `-fexperimental-bounds-safety` is ignored when building with `-x assembler`. However, it won't emit a warning when building with `-x assembler-with-cpp`.
This issue tracks adding a warning to detect when `-fexperimental-bounds-safety` is used with `-x assembler-with-cpp`.
We can either have a generic warning whenever this combination of flags are used. Or we could have a more targeted warning:
E.g.
```
#if __has_feature(bounds_safety) // Should warn here
mov x0, #42
#else
#error "oh no"
#endif
```
