That's a good question.  Possibly as a result of
append_to_statement_list_1 helpfully noticing that if we pass in a
pointer to NULL, it goes ahead and creates a list for us.  This works
nicely for the TREE_CHAIN-based stack, but not so nicely for the
VEC-based stack.

One wonders if the NULL checking in append_to_statement_list_1 could go
away...
