This doesn't support -structurizecfg-skip-uniform-regions since that would require porting LegacyDivergenceAnalysis. The NPM doesn't support adding a non-analysis pass as a dependency of another, so I had to add -lowerswitch to some tests or pin them to the legacy PM. This is the only RegionPass in tree, so I simply copied the logic for finding all Regions from the legacy PM's RGManager into StructurizeCFG::run().
