Finished benchmarking commit (589ad6a): comparison url.

Summary: This change led to large relevant mixed results 🤷 in compiler performance.

• Small improvement in instruction counts (up to -0.4% on incr-unchanged builds of style-servo)
• Large regression in instruction counts (up to 3.9% on incr-unchanged builds of deep-vector)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Next Steps: If you can justify the regressions found in this perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please open an issue or create a new PR that fixes the regressions, add a comment linking to the newly created issue or PR, and then add the perf-regression-triaged label to this PR.
