Research direction
No file, test, or entry point is named in the issue. Start by locating the existing incremental-compilation benchmarks in rustc-perf, then add a case where only a dependency is patched; done means the dependent crate recompiles with unchanged declarations and generic definitions and the benchmark records that scenario.
