This commit causes a regression. I can't build CMake-3.30.5 (the version recommended by spack, the `Source/cmJSONState.cxx` file) when assertions are turned on in LLVM, unless I revert this commit:

```
clang++: llvm/include/llvm/Support/Casting.h:578: decltype(auto) llvm::cast(From *) [To = llvm::IntegerType, From = llvm::Type]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
```
