Address review comments.

Also, emit the declaration of the destructor of a trivial-abi override class in Sema::ActOnParamDeclarator and mark it as referenced. This is necessary because a trivial-abi type that is passed by value needs to be destructed in the callee and the destructor has to be declared in the AST when IRGen emits the call to the destructor in the callee.
