Reexport IntErrorKind in std
Currently `IntErrorKind` can only be found in `core`. @Centril confirmed on Discord that this is unintentional (should I r? him in this situation?).
Should there be a test for this? As far as this *specific* situation goes, I don't think so, I'll risk it and say that there's no way this regresses. However, it might be a good idea to have some tool detect public items in `core` that are not reexported in `std`. Does this belong in tidy, or should that be a separate tool? Is there some rustc-specific *linter*? Unless that's entirely a dumb idea, this should probably get an issue.
Note: My local build hasn't finished yet, but it's well past the point where I would expect problems.
Fix#58270, fix off-by-one error in error diagnostics.
This fixes#58270 by checking if two diagnostics overlap completely when we're calculating the line offset for each message.
Add codegen test for PGO instrumentation.
This PR adds a codegen test that makes sure that LLVM actually generates instrumentation code when we enable PGO instrumentation in `rustc`.
The second commit updates a test case to the new commandline option syntax introduced in #59874. Without the fix the test still works, but it confusingly creates a directory called `test.profraw`, which usually is the name of the _file_ where profiling data is collected.
tweak unresolved label suggestion
Only suggest label names in the same hygiene context, and use a
structured suggestion.
Question for reviewer: Is this the right way to check for label hygiene?
MIR generation cleanup
* Handle the case where the body of a constant is a subtype of the type of the constant (see `mir_static_subtype.rs`).
* Move the evaluation of `ExprKind::Use` into `into.rs`, saving an unnecessary copy.
HirIdification: rework Map
The next iteration of HirIdification (#57578).
- remove `NodeId` from `Entry`
- change `Map::map` to an `FxHashMap<HirId, Entry>`
- base the `NodeId` `Map` methods on `HirId` ones (reverses the current state)
- HirIdify `librustdoc` a little bit (some `NodeId` `Map` methods were converted to work on `HirId`s)
The second change might have performance implications, so I'd do a perf run to be sure it's fine; it simplifies the codebase and shouldn't have an impact as long as the `Map` searches are cached (which is now possible thanks to using `HirId`s).

Temporarily accept [i|u][32|size] suffixes on a tuple index and warn
Fix#60138.
#59553 will need to be kept open to track the change back to rejecting this code a few versions down thee line.
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.
r? @nikomatsakis
Replace HashMap implementation with SwissTable (as an external crate)
This is the same as #56241 except that it imports `hashbrown` as an external crate instead of copying the implementation into libstd.
This includes a few API changes (all unstable):
- `try_reserve` is added to `HashSet`.
- Some trait bounds have been changed in the `raw_entry` API.
- `search_bucket` has been removed from the `raw_entry` API (doesn't work with SwissTable).
