4579ccbc0e Make TREE_NOTHROW use the base.nothrow_flag again 
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:

    	many flags as others.  Move visited and default_def_flag to
