Remove #![allow(rustc::potential_query_instability)] from rustc_infer

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
