Speed up `nearest_common_ancestor`. `nearest_common_ancestor` can be made faster. Here are all the benchmarks where one of the measurements improved by at least 1%. ``` clap-rs-check avg: -4.5% min: -8.8% max: -0.3% clap-rs avg: -2.6% min: -4.5% max: 0.5% script-servo avg: -1.7% min: -3.6% max: 0.0% regression-31157 avg: -1.5% min: -2.6% max: -0.4% hyper avg: -1.2% min: -2.5% max: -0.0% piston-image avg: -1.6% min: -2.5% max: 0.1% regex avg: -1.2% min: -2.2% max: 0.0% issue-46449 avg: -1.8% min: -2.1% max: -0.7% crates.io avg: -1.2% min: -2.1% max: 0.0% hyper-check avg: -1.0% min: -2.1% max: -0.1% clap-rs-opt avg: -1.4% min: -2.0% max: -0.3% piston-image-check avg: -1.2% min: -1.9% max: -0.1% regex-check avg: -0.5% min: -1.8% max: -0.1% syn avg: -1.1% min: -1.7% max: -0.1% tokio-webpush-simple-check avg: -1.1% min: -1.6% max: -0.3% tokio-webpush-simple avg: -1.2% min: -1.6% max: -0.0% helloworld-check avg: -1.4% min: -1.6% max: -1.2% deeply-nested avg: -1.2% min: -1.4% max: -0.8% encoding-check avg: -0.8% min: -1.3% max: -0.3% unify-linearly-check avg: -1.0% min: -1.3% max: -0.8% script-servo-check avg: -0.6% min: -1.3% max: 0.0% regression-31157-check avg: -0.9% min: -1.2% max: -0.7% script-servo-opt avg: -0.5% min: -1.2% max: 0.1% deeply-nested-check avg: -0.8% min: -1.2% max: -0.7% encoding avg: -0.7% min: -1.1% max: -0.3% issue-46449-check avg: -0.9% min: -1.1% max: -0.6% parser-check avg: -0.9% min: -1.1% max: -0.8% html5ever avg: -0.5% min: -1.0% max: -0.0% ``` |
