`StringRef::getAsInteger` has two definitions, in one the `Result` argument is
a `APInt &`, the other is a template. Without the `static_cast` the compilation
fails with:
```
llvm-project/llvm/include/llvm/ADT/StringRef.h:485:13: error: invalid
‘static_cast’ from type ‘llvm::APSInt’ to type ‘long long unsigned int’
```
