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:
commit 87d8f7b67c6a36c37e48e298f26e693520099b1e

(ARGUMENT_PACK_INCOMPLETE_P): Use TREE_ADDRESSABLE instead of

* 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.

Richard Guenther pre-approved the reverting of the TREE_NOTHROW change
line.
Tested on x86_64-unknown-linux-gnu against master and applied to
trunk.
