I start to have the feeling we are writing code like this over and over again.
Some examples:
https://github.com/llvm/llvm-project/blob/df57833ea8a3f527b7941576b4a130ddd4361e61/clang/lib/Analysis/BodyFarm.cpp#L718
https://github.com/llvm/llvm-project/blob/df57833ea8a3f527b7941576b4a130ddd4361e61/clang/lib/AST/ExprConstant.cpp#L8763
But there are more, and I always wonder if they can get out of sync. I wonder
if this is time to introduce some helper functions that can be reused.
