// 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
