[analyzer] Faster hashing of subsequences in CompoundStmts.

Summary: This patches improves the hashing subsequences in CompoundStmts by incrementally hashing all subsequences with the same starting position. This results in a reduction of the time for this constraint while running over SQLite from 1.10 seconds to 0.55 seconds (-50%).
