This makes sure that the tests in clippy_utils are run in CI.
When looking into this I discovered that two tests were failing and
multiple doc tests were failing. This fixes those tests and enables a
few more doc tests.
Remove 'speculative evaluation' of predicates
Performing 'speculative evaluation' introduces caching bugs that
cannot be fixed without invasive changes to projection.
Hopefully, we can win back most of the performance lost by
re-adding 'cache completion'

rustdoc: make `--passes` and `--no-defaults` have no effect
Fixes#91714
One potential issue is that currently there is no stable way to achieve `--document-hidden-items`. This affects test `issue-15347`.
I also had to modify the tests `issue-42875` and `no-compiler-export`. Regardless of combinations of `--document-hidden-items` and `--document-private-items`, I was unable to get these to pass without the modifications. I left behind a comment noting the change.
Eliminate `ObligationCauseData`
This makes `Obligation` two words bigger, but avoids allocating a lot of the time.
I previously tried this in #73983 and it didn't help much, but local timings look more promising now.

Fix `SAFETY` comment tag casing in undocumented_unsafe_blocks
This changes the lint introduced in #7748 to suggest adding a `SAFETY` comment instead of a `Safety` comment.
Searching for `// Safety:` in rust-lang/rust yields 67 results while `// SAFETY:` yields 1072.
I think it's safe to say that this comment tag is written in upper case, just like `TODO`, `FIXME` and so on are. As such I would expect this lint to follow the official convention as well.
Note that I intentionally introduced some casing diversity in `tests/ui/undocumented_unsafe_blocks.rs` to test more cases than just `Safety:`.
changelog: Capitalize `SAFETY` comment in [`undocumented_unsafe_blocks`]
I think that s == "" is the only edge case (as it makes iter.next() return None the first time). The early return is necessary so that the last character of 'out' isn't popped if s == "" && !frag.need_backline
This makes `Obligation` two words bigger, but avoids allocating a lot of
the time.
I previously tried this in #73983 and it didn't help much, but local
timings look more promising now.
The previous implementation used slice::as_mut_ptr_range to derive the
pointer for the spare capacity slice. This is invalid, because that
pointer is derived from the initialized region, so it does not have
provenance over the uninitialized region.

`@rustbot` modify labels: rollup
The code intended to set the IMAGE_SCN_LNK_REMOVE flag for the
.rmeta section, however the value of this flag was set to zero.
Instead use the actual value provided by the object crate.
This dates back to the original introduction of this code in
PR #84449, so we were never setting this flag. As I'm not on
Windows, I'm not sure whether that means we were embedding .rmeta
into executables, or whether the section ended up getting stripped
for some other reason.
Explicitly set no ELF flags for .rustc section
For a data section, the object crate will set the SHF_ALLOC by default, which is exactly what we don't want. Explicitly set sh_flags to zero to avoid this.
I checked with `objdump -h` that this produces the right flags for ELF.
Fixes#92013.
Remove `in_band_lifetimes` from `rustc_infer`
See #91867 for more information.
This crate actually had a typo `'ctx` in one of its functions:
```diff
-pub fn same_type_modulo_infer(a: Ty<'tcx>, b: Ty<'ctx>) -> bool {
+pub fn same_type_modulo_infer<'tcx>(a: Ty<'tcx>, b: Ty<'tcx>) -> bool {
```
Also, I wasn't entirely sure about the lifetimes in `suggest_new_region_bound`:
```diff
pub fn suggest_new_region_bound(
- tcx: TyCtxt<'tcx>,
+ tcx: TyCtxt<'_>,
err: &mut DiagnosticBuilder<'_>,
fn_returns: Vec<&rustc_hir::Ty<'_>>,
```
Should all of those lifetimes really be distinct?
Don't emit RETURN_SELF_NOT_MUST_USE lint if `Self` already is marked as `#[must_use]`
New bug discovered with this lint. Hopefully, this is the last one.

rustdoc: Remove unused `collapsed` field
`render/context` always runs after `run_global_context`, so it was always set to `true`.
This is a holdover from when rustdoc allowed configuring passes, but the `collapse-docs` pass was
removed ages ago, and the ability to configure passes is about to be removed.
Found while reviewing https://github.com/rust-lang/rust/pull/91305.
Update example code for Vec::splice to change the length
The current example for `Vec::splice` illustrates the replacement of a section of length 2 with a new section of length 2. This isn't a particularly interesting case for splice, and makes it look a bit like a shorthand for the kind of manipulations that could be done with a mutable slice.
In order to provide a stronger example, this updates the example to use different lengths for the source and destination regions, and uses a slice from the middle of the vector to illustrate that this does not necessarily have to be at the beginning or the end.
Resolves#92067
Enable `#[thread_local]` for all windows-msvc targets
As it stands, `#[thread_local]` is enabled haphazardly for msvc. It seems all 64-bit targets have it enabled, but not 32-bit targets unless they're also UWP targets (perhaps because UWP was added more recently?). So this PR simply enables it for 32-bit targets as well. I can't think of a reason not to and I've confirmed by running tests locally which pass.
See also #91659
Remove `in_band_lifetimes` from `rustc_middle`
See #91867
This was mostly straightforward. In several places, I take advantage
of the fact that lifetimes are non-hygenic: a macro declares the
'tcx' lifetime, which is then used in types passed in as macro
arguments.
Revert "Temporarily rename int_roundings functions to avoid conflicts"
This reverts commit 3ece63b64e192146fcdd1724e25856a93d7626aa.
This should be okay because #90329 has been merged.

Remove `SymbolStr`
This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences.
