When printing a TREE_VEC, this patch makes its length get printed
alongside its prefix, e.g.

     <tree_vec 0x7ffff6a4d0a0 length 2
         elt 0 ....>

Without a reference to its length, an all-NULL TREE_VEC otherwise looks like
an empty TREE_VEC, since NULL elts don't get printed.  This makes
debugging such TREE_VECs pretty confusing.

Is this OK to commit?

gcc/ChangeLog:

        * print-tree.c (print_node) [TREE_VEC]: Print its length.

OK after the usual bootstrap & regression test.
