13287         (add_pass_instance): ...this.  Document the old way that passes were

13292         the pass's clone method, rather than relying on the XNEW/memcpy
13293         within the former make_pass_instance (now add_pass_instance).
13294         (pass_manager::pass_manager): When invoking next_pass_1, also supply
13295         the initial instance of the current pass within the pass manager.
