// Here we do the dance of replacing the tail call sled with a similar
// sequence as the entry sled, but calls the exit sled instead, so we can
// treat tail call exits as if they were normal exits.
// FIXME: In the future we'd need to distinguish between non-tail exits and
// tail exits for better information preservation.
