Prettify rustc_session with recent conveniences
No functional changes.
I felt like making something beautiful.

Remove hermitkernel targets
RustyHermit now maintains custom json targets, which are distributed with the kernel: https://github.com/hermitcore/libhermit-rs/pull/395
See https://github.com/hermitcore/rusty-hermit/issues/197#issuecomment-1076667961

Remove `Session::one_time_diagnostic`
This is untracked mutable state, which modified the behaviour of queries.
It was used for 2 things: some full-blown errors, but mostly for lint declaration notes ("the lint level is defined here" notes).
It is replaced by the diagnostic deduplication infra which already exists in the diagnostic emitter.
A new diagnostic level `OnceNote` is introduced specifically for lint notes, to deduplicate subdiagnostics.
As a drive-by, diagnostic emission takes a `&mut` to allow dropping the `SubDiagnostic`s.

incr. comp.: Let compiler retry finalizing session directory a few times.
In my local testing this fixed issue https://github.com/rust-lang/rust/issues/86929. I wasn't able to come up with a regression test for it though.

Swap DtorckConstraint to DropckConstraint
This change was made as per suspicion that this struct was never renamed after consistent use of DropCk.
This also clarifies the meaning behind the name of this structure.

resolve: Do not build expensive suggestions if they are not actually used
And remove a bunch of (conditionally) unused parameters from path resolution functions.
This helps with performance issues in https://github.com/rust-lang/rust/pull/94857, and should be helpful in general even without that.

Currently it copies a `KleeneOp` and a `Token` out of a
`SequenceRepetition`. It's better to store a reference to the
`SequenceRepetition`, which is now possible due to #95159 having changed
the lifetimes.

This counters the `NamedMatchVec` size increase from the previous
commit, leaving `NamedMatchVec` smaller than before.
|
|
The `Lrc` is only relevant within `transcribe()`. There, the `Lrc` is
helpful for the non-`NtTT` cases, because the entire nonterminal is
cloned. But for the `NtTT` cases the inner token tree is cloned (a full
clone) and so the `Lrc` is of no help.
This commit splits the `NtTT` and non-`NtTT` cases, avoiding the useless
`Lrc` in the former case, for the following effect on macro-heavy
crates.
- It reduces the total number of allocations a lot.
- It increases the size of some of the remaining allocations.
- It doesn't affect *peak* memory usage, because the larger allocations
are short-lived.
This overall gives a speed win.

add diagnostic items for clippy's `trim_split_whitespace`
Adding the following diagnostic items:

* str_trim,
* str_trim_start,
* str_trim_end

debuginfo: Fix debuginfo for Box<T> where T is unsized.
Before this fix, the debuginfo for the fields was generated from the struct defintion of Box<T>, but (at least at the moment) the compiler pretends that Box<T> is just a (fat) pointer, so the fields need to be `pointer` and `vtable` instead of `__0: Unique<T>` and `__1: Allocator`.
This is meant as a temporary mitigation until we can make sure that simply treating Box as a regular struct in debuginfo does not cause too much breakage in the ecosystem.

Try to evaluate in try unify and postpone resolution of constants that contain inference variables
We want code like that in [`ui/const-generics/generic_const_exprs/eval-try-unify.rs`](https://github.com/rust-lang/rust/compare/master...b-naber:eval-in-try-unify?expand=1#diff-8027038201cf07a6c96abf3cbf0b0f4fdd8a64ce6292435f01c8ed995b87fe9b) to compile. To do that we need to try to evaluate constants in `try_unify_abstract_consts`, this requires us to be more careful about what constants we try to resolve, specifically we cannot try to resolve constants that still contain inference variables.

Clarify which kinds of MIR are allowed during which phases.
This enhances documentation with these details and extends the validator to check these requirements more thoroughly. Most of these conditions were already being checked.
There was also some disagreement between the `MirPhase` docs and validator as to what it meant for the `body.phase` field to have a certain value. This PR resolves those disagreements in favor of the `MirPhase` docs (which is what the pass manager implemented), adjusting the validator accordingly. The result is now that the `DropLowering` phase begins with the end of the elaborate drops pass, and lasts until the beginning of the generator lowring pass. This doesn't feel entirely natural to me, but as long as it's documented accurately it should be ok.

Fix ice when error reporting recursion errors

And `crate_lint`/`record_used` to `finalize`
|
|
|
|
Do not construct or pass unused data
|
|
Also remove a redundant parameter from `fn resolve_path(_with_ribs)`, `crate_lint: CrateLint` is a more detailed version of `record_used: bool` with `CrateLint::No` meaning `false` and anything else meaning `true`.

Separate const prop lints from optimizations
r? `@oli-obk`
Separates lints and optimizations during const prop by moving the lints into their own file and checking them during post borrowck cleanup.

Change Thir to lazily create constants
To allow `AbstractConst`s to work with the previous thir changes we made and those we want to make, i.e. to avoid problems due to `ValTree` and `ConstValue` conversions, we instead switch to a thir representation for constants that allows us to lazily create constants.

Properly track `ImplObligations`
Instead of probing for all possible `impl`s that could have caused an
`ImplObligation`, keep track of its `DefId` and obligation spans for
accurate error reporting.
Follow to #89580. Addresses #89418.

This enhances documentation with these details and extends the validator to check these requirements
more thoroughly. As a part of this, we add a new `Deaggregated` phase, and rename other phases so
that their names more naturally correspond to what they represent.

interpret/memory: simplify check_and_deref_ptr
*Finally* I saw a way to make this code simpler. The odd preprocessing in `let ptr_or_addr =` has bothered me since forever, but it actually became unnecessary in the last provenance refactoring. :)
This also leads to slightly more explicit error messages as a nice side-effect. :tada:

Better errors when a Copy impl on a Struct is not self-consistent
As discovered in a Zulip thread with `@nnethercote` and `@Mark-Simulacrum,` it's not immediately obvious why a field on an ADT doesn't implement `Copy`. This PR attempts to give slightly more detailed information by spinning up a fulfillment context to try to dig down and discover transitive fulfillment errors that cause `is_copy_modulo_regions` to fail on a ADT field.
The error message still kinda sucks, but should only show up in the case that an existing error message was totally missing... so I think it's a good compromise for now?

diagnostics: do not suggest `fn foo({ <body> }`
Instead of suggesting that the body always replace the last character on the line, presuming it must be a semicolon, the parser should instead check what the last character is, and append the body if it is anything else.
Fixes #83104
