10/// This file declares the class VPlanVerifier, which contains utility functions
11/// to check the consistency of a VPlan. This includes the following kinds of
12/// invariants:
13///
14/// 1. Region/Block invariants:
15/// - Region's entry/exit block must have no predecessors/successors,
16/// respectively.
17/// - Block's parent must be the region immediately containing the block.
18/// - Linked blocks must have a bi-directional link (successor/predecessor).
19/// - All predecessors/successors of a block must belong to the same region.
20/// - Blocks must have no duplicated successor/predecessor.
