Disable hash-table sanitization for mem stats maps. 

2019-06-12  Martin Liska  <mliska@suse.cz>

	* ggc-common.c (ggc_prune_overhead_list): Do not sanitize
	the created map.
	* hash-map.h: Add sanitize_eq_and_hash into ::hash_map.
	* mem-stats.h (mem_alloc_description::mem_alloc_description):
	Do not sanitize created maps.
