`thir`: Add `Become` expression kind
This PR is pretty small and just adds `thir::ExprKind::Become`. I didn't include the checks that will be done on thir, since they are much more complicated and can be done in parallel with with MIR (or, well, at least I believe they can).

Export AnalysisResults trait in rustc_mir_dataflow
Followup to https://github.com/rust-lang/rust/pull/108293
Re-exports the new trait defined in mentioned PR to make ResultsCursor::seek_before_primary_effect, ResultsCursor::seek_after_primary_effect... usable again outside the compiler itself.
Use `CoverageKind::as_operand_id` instead of manually reimplementing it
These two pieces of code are functionally equivalent to the `CoverageKind::as_operand_id` method that already exists, and is already used elsewhere in this file.
This slightly reduces the amount of code that manually pattern-matches on `CoverageKind`.
bootstrap: rename 'user' profile to 'dist'
Fixes#112074
Unfortunately a big chunk of the diff is adding `PartialEq/Eq/Debug` impls so we can `assert_eq` but I think better to have them in the long run.
For back compat, ensure `"maintainer"`, `"user"` and `"dist"` are all parsed as `Profile::Dist`.

Migrate `TyCtxt::predicates_of` and `ParamEnv::caller_bounds` to `Clause`
The last big change in the series.
I will follow-up with additional filed issues once this PR lands:
- [ ] Investigate making `TypeFoldable<TyCtxt<'tcx>> for ty::Clause<'tcx>` implementation less weird: 2efe091705/compiler/rustc_middle/src/ty/structural_impls.rs (L672)
- [ ] Clean up the elaborator since it should only be emitting child clauses, not predicates
- [ ] Rename identifiers like `pred` and `predicates` to `clause` if they're actually clauses around the codebase
- [ ] Validate that all of the `ToPredicate` impls are acutally still needed, or prune them if they're not

rustdoc: render generic params & where-clauses of cross-crate assoc tys in impls
We used to only ever render generic parameters & where-clauses of cross-crate associated types when the item was located inside of a trait and we used to just drop them when it was inside of an impl block (trait or inherent).
Fixes#112904.
`@rustbot` label A-cross-crate-reexports
remove unused field
Followup to #104455. The field is no longer needed since ExtractIf (previously DrainFilter) doesn't keep draining in its drop impl.
`hir`: Add `Become` expression kind (explicit tail calls experiment)
This adds `hir::ExprKind::Become` alongside ast lowering. During hir-thir lowering we currently lower `become` as `return`, so that we can partially test `become` without ICEing.

Switch some more Steps to `builder.msg`
In particular, this hides compiletest suites under a dropdown - some builders are configured with `verbose-tests`, which makes the suites take up many thousands of lines.

doc: loongarch: Update maintainers
My colleague, `@zhaixiaojuan,` has been completely occupied with other matters and is no longer in charge of Rust. Consequently, I intend to update the maintainers in the platform documentation to avoid causing any disruptions for her and to ensure that relevant notifications regarding LoongArch are promptly directed to the appropriate developers.
