// This file defines the ScopPass class. ScopPasses are just RegionPasses,
// except they operate on Polly IR (Scop and ScopStmt) built by ScopInfo Pass.
// Because they operate on Polly IR, not the LLVM IR, ScopPasses are not allowed
// to modify the LLVM IR. Due to this limitation, the ScopPass class takes
// care of declaring that no LLVM passes are invalidated.
