a962274903 Search for incompatible universes in borrow errors 
If we have a borrow that has to live for `'static` we need to check for
any regions in incompatible universes when trying to find the cause.

Rollup merge of #56278 - eddyb:mir-debuginfo-proof, r=nikomatsakis 
Future-proof MIR for dedicated debuginfo.

This is #56231 without the last commit (the one that actually moves to `VarDebuginfo`).
Nothing should be broken, but it should no longer depend on debuginfo for anything else.

Rollup merge of #59856 - albins:update-polonius, r=nikomatsakis 
update polonius-engine

This updates polonius-engine to [version 0.7.0](https://github.com/rust-lang/polonius/blob/master/RELEASES.md#v070), which adds a hybrid algorithm that starts off with performing a cheaper, location-insensitive analysis before proceeding with the full analysis.

Use normal newtype_index macro for MIR dataflows

* Makes the definition of these structs contain `struct IndexName`
* Avoids having an offset by removing high values, rather than 0
* Implements some traits for us.

Rollup merge of #59630 - nnethercote:shrink-mir-Statement, r=pnkfelix 
Shrink `mir::Statement`.

The `InlineAsm` variant is extremely rare, and `mir::Statement` often
contributes significantly to peak memory usage.

Rollup merge of #59514 - tmandry:remove-adt-def-from-projection-elem, r=eddyb 
Remove adt_def from projections and downcasts in MIR

As part of optimizing generator layouts in MIR, we'd like to allow downcasting generators to variants which do not have a corresponding `def_id`, since they are created by the compiler.

This refactor hopes to allow that, without regressing perf.

Fallback to `static_impl_trait` for nice error message by peeking at the
return type and the lifetime type. Point at the return type instead of
the return expr/stmt in NLL mode.

HirIdification: kill off NodeId stragglers

The final stages of HirIdification (#57578).

This PR, along with https://github.com/rust-lang/rust/pull/59042, should finalize the HirIdification process (at least the more straightforward bits).

- replace `NodeId` with `HirId` in `trait_impls`
- remove all `NodeId`s from `borrowck`
- remove all `NodeId`s from `typeck`
- remove all `NodeId`s from `mir`
- remove `trait_auto_impl` (unused)

I would be cool to also remove `NodeId` from `hir::def::Def`, `middle::privacy::AccessLevel`  and `hir::ItemId`, but I don't know if this is feasible.

I'll be happy to do more if I've missed anything.
