// layout randomization affects the hir stat output
//@ needs-deterministic-layouts
// Type layouts sometimes change. When that happens, until the next bootstrap
// bump occurs, stage1 and stage2 will give different outputs for this test.
// Add an `ignore-stage1` comment marker to work around that problem during
// that time.
// The aim here is to include at least one of every different type of top-level
// AST/HIR node reported by `-Zhir-stats`.
