I see, there is Asan case already and we need kernel one

there is already one 
```
AsanUseAfterScope = Args.hasFlag(
        options::OPT_fsanitize_address_use_after_scope,
        options::OPT_fno_sanitize_address_use_after_scope, AsanUseAfterScope);
```

can you instead move that out from asas case and do single:


if (asan || kasan) {
AsanUseAfterScope = Args.hasFlag(
        options::OPT_fsanitize_address_use_after_scope,
        options::OPT_fno_sanitize_address_use_after_scope, AsanUseAfterScope);
} else {
AsanUseAfterScope = false
}
