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:

cp/
* cp-tree.h (TREE_INDIRECT_USING): Use TREE_LANG_FLAG_0 accessor.
(ATTR_IS_DEPENDENT): Likewise.
(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
common bits section in exchange for saturating_flag and
unsigned_flag. Add SSA name version and tree vec length
fields here.
(struct tree_vec): Remove length field here.
(struct tree_ssa_name): Remove version field here.
