* class.c (registered_class): Take it out of class_roots; turn into
        a vec of trees.
        (register_class): Make static.  Don't duplicate decl node.  Use
        VEC_safe_push.
        (emit_register_classes): Use VEC_iterate.  Use output_constant
        instead of assemble_integer.  Don't call mark_decl_referenced
        directly.
        * java-tree.h (register_class): Remove decl.
