	* hash-table.h (class hash_table): Use a descriptor template
	argument instead of decomposed element type and support
	functions.
	(struct pointer_hash): New generic typed pointer-hash.
	(struct typed_free_remove, struct typed_noop_remove): Generic
	hash_table support pieces.
	* coverage.c (struct counts_entry): Add hash_table support
	members.
