I would recommend adding it to `UnreachableCode` as I don't see this being a 
particularly aggressive unreachable warning. FWIW, I would be opposed to 
dropping the diagnostic entirely as the standard recommends diagnosing an 
unreachable fallthrough statement 
(https://eel.is/c++draft/dcl.attr.fallthrough#2.sentence-2 and the similar 
wording in C2x 6.7.11.5p3.
