This helps transition code bases to handle the new warning added in 3632e2f517
Before:
```
clang/test/FixIt/format.cpp:10:16: warning: format specifies type 'int' but the argument has type 'N::E' [-Wformat]
10 | printf("%d", N::E::One); // expected-warning{{format specifies type 'int' but the argument has type 'N::E'}}
| ~~ ^~~~~~~~~
| %d
```
After:
```
clang/test/FixIt/format.cpp:10:16: warning: format specifies type 'int' but the argument has type 'N::E' [-Wformat]
10 | printf("%d", N::E::One); // expected-warning{{format specifies type 'int' but the argument has type 'N::E'}}
| ~~ ^~~~~~~~~
| static_cast<int>( )
```
