----------------
Updating the old function's type here can potentially violate our AST invariants, especially in C++17 where it will change the canonical type of the function. You would need to at least notify AST mutation listeners, and iterate over all previous declarations rather than only updating one of them. (You're also throwing away things like calling conventions here.)

`Sema::UpdateExceptionSpec` handles these details for you.
