Hi, I'm curious how it would affect the getTerminator() method of a basic block? I.e., how would one find the terminating instruction in that case? By iterating over all of them or ...?

Going to keep this RFC short and to the point: TerminatorInst doesn't pull its weight in the type system. There is essentially a single relevant API -- iterating successors. There is no other interesting aspect shared -- the interface itself just dispatches to specific instructions to be implemented. On the flip side, CallInst and InvokeInst have *massive* amounts of code shared and struggle
