        Rewrite how instances of passes are cloned to remove assumptions
        about their sizes (thus allowing pass subclasses to have
        additional data fields, albeit non-GC-managed ones at this point).

        * passes.c (make_pass_instance): Now that passes have clone
        methods, rewrite this function to eliminate XNEW and memcpy
        calls that used hardcoded sizes.  Since this function no longer
        creates pass instances, rename it to...
        (add_pass_instance): ...this.  Document the old way that passes were
        numbered and flagged, and rework this function to continue using it.
        (next_pass_1): Add an initial_pass argument for use by
        add_pass_instance.
        (position_pass): When adding multiple instances of a pass, use
        the pass's clone method, rather than relying on the XNEW/memcpy
        within the former make_pass_instance (now add_pass_instance).
        (pass_manager::pass_manager): When invoking next_pass_1, also supply
        the initial instance of the current pass within the pass manager.

        This is the automated part of the conversion of passes from C
        structs to C++ classes.
