This happens on clang assertions trunk but not on clang-19 and before
I've reduced the test to a small program with the ```_Atomic``` keyword
```c
int main ( ) { 
 int c = ( _Atomic short  ) 1 + 2; 
    return 0; 
} 
 ```
```
clang: /root/llvm-project/clang/lib/AST/ExprConstant.cpp:11793: bool {anonymous}::IntExprEvaluator::Success(const llvm::APSInt&, const clang::Expr*, clang::APValue&): Assertion `E->getType()->isIntegralOrEnumerationType() && "Invalid evaluation result."' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
