// In flang pipeline, the inliner calls createCanonicalizerPass with the region
// simplification disabled. The inliner pass does canonicalization even if
// no inlining happens. After canonicalization, FIR lite region simplification
// must be called to get rid of unreachable regions.
// This code exposes the need to run SimplifyRegionLitePass after the inliner is
// called with FIR pipeline.
