Fix integer overflow in stats of trees.

2018-01-12  Martin Liska  <mliska@suse.cz>

	* tree-core.h: Use uint64_t instead of int.
	* tree.c (tree_node_counts): Likewise.
	(tree_node_sizes): Likewise.
	(dump_tree_statistics): Use PRIu64 in printf format.

+
 	* Makefile.in: As qsort_chk is implemented in vec.c, add
 	vec.o to linkage of gencfn-macros.
 	* tree.c (build_new_poly_int_cst): Add CXX_MEM_STAT_INFO as it's
