Overall result: ❌✅ regressions and improvements - ACTION NEEDED

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.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

The result seems okayish to me. In instructions count, it seems the primary improvements overweight the primary regressions. The regressions in secondary benchmarks, specially the memory ones, don't seem to be that good, but I guess they are acceptable?

I have changed shift_remove to remove following the conversation in #102674. It should be better for the performance and still work, because we only care about the reproducibility and not about having an certain order.

Remove #![allow(rustc::potential_query_instability)] from rustc_infer
e950201 
Change reported_violations to use IndexSet

It is being used to iterate and to insert, without a lot of lookups
so hopefully it won't be a perf hit

Change MiniGraph.nodes to use IndexSet

It is being used to iterate and to insert, without performing lookups
so hopefully it won't be a perf hit

Change RegionConstraintData.givens to a FxIndexSet

This might result in a perf hit. Remove was being used in `givens`,
and `FxIndexSet` doesn't allow calling remove without losing the
fixed iteration order. So it was necessary to change remove to
`shift_remove`, but this method is slower.

Change OpaqueTypesVisitor to use stable sets and maps

This could also be a perf hit.

Make TraitObject visitor use a stable set
