Summary: Unused deduction guides in anonymous namespaces or for nested classes trigger `-Wunused-function`.
Example error message:
```
<source>:12:3: error: unused function '<deduction guide for Bar>' [-Werror,-Wunused-function]
12 | Bar() -> Bar<0>;
| ^~~
```
Reproducer: https://godbolt.org/z/zW1KWdK84
This is basically the same failure mode as https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106604.
Appears to occur on all existing releases of clang.
