Don't use bytepos offsets when computing semicolon span for removal
Causes problems when we recover confusable characters w/ a different byte width
Fixes#123607
Clean up tests/ui by removing `does-nothing.rs`
In [a previous PR](https://github.com/rust-lang/rust/pull/123297#issuecomment-2039887806), it was suggested that this test be removed:
> it's testing a basic diagnostic for an unknown variable (added over a decade ago for https://github.com/rust-lang/rust/issues/154) that is already covered by probably dozens or hundreds of other tests.
It was then suggested that [opening a new PR](https://github.com/rust-lang/rust/pull/123563#discussion_r1554654102) for this would be more organized.
I'm setting this as a draft, as:
1. The tests/ui directory is rather disorganized, a large quantity of tests are not even contained inside their own directories. This PR could turn into "clean up the UI tests directory", if I were to place everything into categories (for example, everything related to CLI flags could get placed in a cli directory).
2. This will have a merge conflict with #123563 should that get merged. I trust that _this time_, I won't run into [The Incident](https://github.com/rust-lang/rust/pull/123297#issuecomment-2041137569) while rebasing. Edit: Yay, I did it properly!
Unconditionally show update nightly hint on ICE
Instead of trying to guess if a update nightly hint should be shown (by checking for system time, querying version and channel info etc.), just show the update nightly hint for nightly compilers. This avoids breaking tests that match on ICE test outputs on nightly/dev channels.
> Another issue is that the outdated nightly hint triggers for ICE tests, causing a mismatch with the test expectation. There doesn't seem to be any env var to suppress this.

When suggesting a type on inference error, do not use `{closure@..}`.
Instead, replace with an appropriate `fn` ptr.
On the error message, use `short_ty_string` and write long types to
disk.

Fix#123630.
Unify the output of `suggest_assign_value` and `ty_kind_suggestion`.
Ideally we'd make these a single function, but doing so would likely require modify the crate dependency tree.
This commit does three things:
1. replaces (the last remaining) never true cfgs by the FALSE cfg
2. fix derive-helper-configured.rs (typo in directive)
3. and comment some current unused #[cfg_attr] (missing revisions)
I added this back in 111999, but I no longer think it's a good idea
- It had to get scaled back to only power-of-two things to not break a bunch of targets
- LLVM seems to be getting better at memcpy removal anyway
- Introducing vector instructions has seemed to sometimes (115515) make autovectorization worse
So this removes it from the codegen crates entirely, and instead just tries to use <https://doc.rust-lang.org/nightly/nightly-rustc/rustc_codegen_ssa/traits/builder/trait.BuilderMethods.html#method.typed_place_copy> instead of direct `memcpy` so things will still use load/store for immediates.
Don't rely on upvars being assigned just because coroutine-closure kind is assigned
Previously, code relied on the implicit assumption that if a coroutine-closure's kind variable was constrained, then its upvars were also constrained. This is because we assign all of them at once at the end up upvar analysis.
However, there's another way that a coroutine-closure's kind can be constrained: from a signature hint in closure signature deduction. After #123350, we use these hints, which means the implicit assumption above no longer holds.
This PR adds the necessary checks so that we don't ICE.

Stop making any assumption about the projections applied to the upvars in the `ByMoveBody` pass
So it turns out that because of subtle optimizations like [`truncate_capture_for_optimization`](ab5bda1aa7/compiler/rustc_hir_typeck/src/upvar.rs (L2351)), we simply cannot make any assumptions about the shape of the projections applied to the upvar locals in a coroutine body.
So stop doing that -- the code is resilient to such projections, so the assertion really existed only to "protect against the unknown".

Split `non_local_definitions` lint tests in separate test files
This PR splits the giant `non_local_definitions` lint UI test in separate test files.
This change is extracted from #123594 (where it was requested https://github.com/rust-lang/rust/pull/123594#discussion_r1555261772), to ease the review of the other PR and to reduce the size of the other PR.

rustdoc: synthetic auto: filter out clauses from the implementor's ParamEnv
... not just the elaborated clauses.
Fixes another regression introduced by me in #123340, oops!
Fixes https://github.com/rust-lang/rust/pull/123340#issuecomment-2034195786, cc ``@tamird.``
An earlier local iteration of branch `rustdoc-simplify-auto-trait-impl-synth` (PR #123340) contained a fix for issue #111101 before I decided to limit the scope. I must've introduced this bug when manually reverting that part of the code.

Fix UI tests with dist-vendored dependencies
There is already a workaround in `compiletest` to deal with custom
`CARGO_HOME` using `-Zignore-directory-in-diagnostics-source-blocks={}`.
A similar need exists when dependencies come from the local `vendor`
directory, which distro builds often use, so now we ignore that too.
Also, `issue-21763.rs` was normalizing `hashbrown-` paths, presumably
expecting a version suffix, but the vendored path doesn't include the
version. Now that matches `[\\/]hashbrown` instead.
KCFI: Use legal charset in shim encoding
To separate `ReifyReason::FnPtr` from `ReifyReason::VTable`, we hyphenated the shims. Hyphens are not actually legal, but underscores are, so use those instead.

[rustdoc] [GUI tests] Make theme switching closer to reality
Better to actually perform actions user do rather than only testing the change through local storage.
As for `browser-ui-test` update: I updated `puppeteer` version (to `0.19.4`) and fixed a bug when displaying the file if it came from an `include`.

Re-enable the early otherwise branch optimization
Closes#95162. Fixes#119014.
This is the first part of #121397.
An invalid enum discriminant can come from anywhere. We have to check to see if all successors contain the discriminant statement. This should have a pass to hoist instructions.
r? cjgillot
Before this fix, the call to `body()` would crash, since `has_body()`
would return true, but we would try to retrieve the body of an intrinsic
which is not allowed.
Instead, the `Instance::body()` function will now convert an Intrinsic
into an Item before retrieving its body.
This change uses the same "exact" paths as trait implementors
and type alias inlining to track items with multiple
reachable paths. This way, if you search for `vec`, you get
only the `std` exports of it, and not the one from `alloc`.
It still includes all the items in the search index so that
you can search for them by all available paths. For example,
try `core::option` and `std::option`, and notice that the
results page doesn't show duplicates, but still shows all
the items in their respective crates.
Pass list of defineable opaque types into canonical queries
This eliminates `DefiningAnchor::Bubble` for good and brings the old solver closer to the new one wrt cycles and nested obligations. At that point the difference between `DefiningAnchor::Bind([])` and `DefiningAnchor::Error` was academic. We only used the difference for some sanity checks, which actually had to be worked around in places, so I just removed `DefiningAnchor` entirely and just stored the list of opaques that may be defined.
