Ezgi Çiçek f80af7be93 Fix control var analysis for loops with multiple back-edges per loop head ... Summary: I realized that control variable analysis was broken when we had multiple back-edges for the same loop. This is often the case when we have a switch statement combined with continue in a loop (see `test_switch` in `switch_continue.c`) or when we have disjunctive guards in do-while loops. This diff fixes that by - defining a loop by its loophead (the target of its backedges) rather than its back-edges. Then it converts back-edge list to a map from loop_head to sources of the loop's back-edges. - collecting multiple guard nodes that come from potentially multiple exit nodes per loop head In addition, it also removes the wrong assumption that an exit node belongs to a single loop head.
