+DenseSet is a simple quadratically probed hash table.  It excels at supporting
+small values: it uses a single allocation to hold all of the pairs that
+are currently inserted in the set.  DenseSet is a great way to unique small
+values that are not simple pointers (use <a 
+href="#dss_smallptrset">SmallPtrSet</a> for pointers).  Note that DenseSet has
+the same requirements for the value type that <a 
+href="#dss_densemap">DenseMap</a> has.
