Fangrui Song 7588cf09da [ELF] Use union-find set and doubly linked list in Call-Chain Clustering (C³) heuristic 
Before, SecToClusters[*] was used to track the belonged cluster.
During a merge (From -> Into), every element of From has to be updated.
Use a union-find set to speed up this use case.

Also, replace `std::vector<int> Sections;` with a doubly-linked
pointers: int Next, Prev;
