Summary: This benchmark run did not return any relevant results.

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

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Revert "Check that closures satisfy their where bounds"

This reverts commit 253408b from rust-lang#96899

This is only performed on beta to give us another few weeks to fix rust-lang#97607 on nightly. The planned fix is likely way too large to backport anyway.
