part_traits in cfgexpand.c needs to use the value rather than the key to
represent empty and deleted slots.  What it's doing is pretty generic,
so this patch adds a helper class to hash-map-traits.h.


gcc/
	* hash-map-traits.h (unbounded_hashmap_traits): New class.
	(unbounded_int_hashmap_traits): Likewise.
	* cfgexpand.c (part_traits): Use unbounded_int_hashmap_traits.

OK.
