Cleanup class_decl inifite comparison detection

We recently used a new type interned_string_set_type to detect
infinite comparison of function_type type.  This patch uses the same
type for class_decl infinite comparison detection.

	* src/abg-ir.cc (environment::priv::classes_being_compared_): Make
	this use the new interned_string_set_type type.
	(class_decl::priv::{mark_as_being_compared, comparison_started}):
	Adjust.
