Subject: hash-traits.h (default_hash_traits): New structure.

gcc/
	* hash-traits.h (default_hash_traits): New structure.
	* hash-set.h (default_hashset_traits): Delete.
	(hash_set): Use default_hash_traits<Key> instead of
	default_hashset_traits.  Delete hash_entry type and use Key directly.
	* ipa-devirt.c (pair_traits): Delete.
	(default_hash_traits <type_pair>): Override.
	(odr_subtypes_equivalent_p): Remove pair_types template parameter.
	(odr_types_equivalent_p, add_type_duplicate): Likewise.
