mem-stats.h (struct mem_usage): Use PRIu64 for printing size_t.

2016-02-23  Richard Biener  <rguenther@suse.de>

	* mem-stats.h (struct mem_usage): Use PRIu64 for printing size_t.
	* bitmap.h (struct bitmap_usage): Likewise.
	(bitmap_move): Declare.
	* bitmap.c (register_overhead): Take size_t argument.
	(bitmap_move): New function.
	* df-problems.c (df_rd_transfer_function): Use bitmap_move
	to properly account overhead.
	* tree.c (free_node): Use tree_size.
