    • Make TREE_NOTHROW use the base.nothrow_flag again · 4579ccbc 
      While working on something else, I noticed that debug_tree (vec), when
vec is a TREE_VEC was crashing because TREE_NOTHROW was asserting that
its argument is not a TREE_VEC, so print_node would crash.

It turned out that TREE_NOTHROW was accidentally modified by this
change set:

    	(ARGUMENT_PACK_INCOMPLETE_P): Use TREE_ADDRESSABLE instead of
    	TREE_LANG_FLAG_0 on TREE_VECs.

    	* tree.h (struct tree_base): Add union to make it possible to
    	re-use the upper 4 bytes for tree codes that do not need as
    	many flags as others.  Move visited and default_def_flag to
