Improve span for `consider adding an explicit lifetime bound` suggestions under NLL
Because NLL borrowck is run after typeck, `in_progress_typeck_results` was always `None` which was preventing the retrieval of the span to which the suggestion is suppose to add the lifetime bound.
We now manually pass the `LocalDefId` owner to `construct_generic_bound_failure` so that under NLL, we give the owner id of the current body.
This helps with #96332
Improve bootstrap tests
- Don't checkout submodules in bootstrap tests
This doesn't cause any tests to fail, and can greatly speed them up.
- Add a test for --exclude test::XXX
I didn't know that the `test::` syntax was valid before, and it doesn't seem to be documented anywhere. Add a test so it doesn't regress accidentally, and as executable documentation.
This also moves the `exclude` tests out of `dist`, to avoid assertion errors when the `cmd` passed to configure didn't match the `subcommand` used.
- Use run_build helper consistently across most bootstrap tests
This is not super important to do, but the consistency is nice.
I didn't change any tests that call `configure("dist")` and then override the subcommand - doing
that at all is pretty sketchy, but I don't want to mess with it while already doing a refactor.
Found while working on the "one call to Step for all paths" change mentioned in https://github.com/rust-lang/rust/pull/95503#issuecomment-1105914384, but independent of that work.
cc `@pietroalbini` for the `--exclude` test, git blame says you added support for it originally.
Add `x {check,build,doc} {compiler,library}` aliases.
While working on https://github.com/rust-lang/rust/pull/95503, I realized that it will interfere with existing command lines:
Currently people run `x build library/std` expecting it to "add all library crates to the sysroot",
but after that change, it will *only* build `libstd` and its dependencies (and add them to the sysroot), not libtest or libproc_macro.
That will work for local testing in most cases, but could be confusing. Even if not, though, I think `x build library` is more clear about what actually happens than the current `x build library/std`.
The intended end goal is something like:
- For check/build/doc, we have library + compiler aliases, which correspond to basically "most possible" for that piece. This is the intended path of entry (rather than library/test or similar as today) for when you just want the thing to work -- for example, getting a compiler that is "crates.io-compatible" would be roughly `x.py build library`). #95504
- Specific crate invocations build up to that crate, which means that if you don't care about tests you probably want x.py build library/proc_macro or library/std for faster build times. #95503
Note that this is already implemented today for the `doc` command and seems to work pretty well in practice.
I plan to change the dev-guide and various instructions in the README to `build library` once this is merged.

Previously this lint would only look at the integer part of floating
point literals without an exponent, giving wrong suggestions like:
```
|
8 | let _ = 123_32.123;
| ^^^^^^^^^^ help: did you mean to write: `123.123_f32`
|
```
Instead, it now ignores these literals.
Fixes#6129
Instead of just always suggesting signed suffixes regardless of size
of the value, it now suggests an unsigned suffix when the value wouldn't
fit into the corresponding signed type, and ignores the literal entirely
if it is too big for the unsigned type as well.
make `classify_drop_access_kind` iterate
This PR:
1. fixes the FIXME of `classify_drop_access_kind` func in the borrowck part. The process of obtaining `StorageDeadOrDrop` has been changed from recursive to iterative.
2. gets `place_ty` in each iteration, avoid repeatedly getting the `ty` of the same place (O(n^2) => O(n))
wrong_self_convention allows `is_*` to take `&mut self`
fix#8480 and #8513
Allowing `is_*` to take `&self` or none is too restrictive.
changelog: FPs: [`wrong_self_convention`] now allows `&mut self` and no self as arguments for `is_*` methods

Add support for `nounused` --extern flag
This adds `nounused` to the set of extern flags:
`--extern nounused:core=/path/to/core/libcore.rlib`.
The effect of this flag is to suppress `unused-crate-dependencies`
warnings relating to the crate.

Optimize `const_prop` mir-opt by accessing `local_decls` through `ecx`
From the FIXME in the impl of `ConstPropagator`. Accessing `local_decls` and `scource_scopes` from `ecx` can reduce `clone` calls and save compile time.
Besides, according to #96213 , the FIXME about writing `layouts` to `ecx` in advance can also be removed.
Remove visibility information from HIR
The resolver exports all the necessary visibility information through the `tcx.visibility` query.
This PR stops having a dedicated visibility field in HIR, in order to use this query.
We keep a `vis_span` field for diagnostic purposes.
When suggesting the use of a fully qualified path for a method call that
is ambiguous because it has multiple candidates, erase type params in
the resulting code, as they would result in an error when applied. We
replace them with `_` in the output to rely on inference. There might be
cases where this still produces slighlty incomplete suggestions, but it
otherwise produces many more errors in relatively common cases.
Fix#96292
Unstably constify `impl<I: Iterator> IntoIterator for I`
This constifies the default `IntoIterator` implementation under the `const_intoiterator_identity` feature.
Tracking Issue: #90603
No "weird" floats in const fn {from,to}_bits
I suspect this code is subtly incorrect and that we don't even e.g. use x87-style floats in CTFE, so I don't have to guard against that case. A future PR will be hopefully removing them from concern entirely, anyways. But at the moment I wanted to get this rolling because small questions like that one seem best answered by review.
