Ah yes, that is on purpose. All AST nodes (and everything stored in them) must
be trivially destructible. The AST nodes are all allocated in a bump pointer
allocator, so to free them, we just free that allocator. That also means that
you can never put e.g. a `SmallVector` in an AST node (or anything else that
has a non-trivial destructor).
