While it would technically be possible to workaround this in cg_clif, it
quickly becomes very messy and would likely cause correctness issues.
Working around it in rustc instead is much simper and won't have any
negative impact for code running on stable as vectors smaller than
128bit can only be made on nightly using core::simd or #[repr(simd)].
Roses are red,
Biolets are blue,
A typo happened,
too late now
You might be asking,
what are Biolets now?
And to be honest,
I have no clue

Don't store a redundant span in user-type projections
While experimenting with some larger changes, I noticed that storing this span here is unnecessary, because it is also present in the corresponding `CanonicalUserTypeAnnotation` and can be retrieved via the annotation's ID.
Implement accepted ACP for functions that isolate the most significant
set bit and least significant set bit on unsigned, signed, and NonZero
integers.
Add function `isolate_most_significant_one`
Add function `isolate_least_significant_one`
Add tests
Emit `trunc nuw` for unchecked shifts and `to_immediate_scalar`
- For shifts this shrinks the IR by no longer needing an `assume` while still providing the UB information
- Having this on the `i8`→`i1` truncations will hopefully help with some places that have to load `i8`s or pass those in LLVM structs without range information
I had to do a lot of debug by printing; having these `Debug` traits in
place made it easier. Additionally, add some more information to
existing `info!` statements.
Introduce an enum that represents the different possible sources for
dependencies, and use them where possible. This will enable more fine
grained control and provides better context than passing the `dep_root`
tuple.
Use this to ensure that injected crates always show up as private by
default.
Bump sccache in CI to 0.9.1
We haven't updated the used sccache version for years, it has accrued a bunch of fixes and features in the meantime. It now supports the `--show-adv-stats` flag, which gives a more detailed summary of the results of caching. And it can also cache Rust code, which could be useful in the future (https://github.com/rust-lang/rust/pull/136942 - although now there are no large wins).
It also supports caching PGO now, but since the PGO profiles are always different, it won't make any real difference.
https://github.com/rust-lang/rust/pull/133076 previously tried to update the version to 0.3 (CC `@klensy)`

`Postorder` has a `C: Customization<'tcx>` parameter, that gives it
flexibility about how it computes successors. But in practice, there are
only two `impls` of `Customization`, and one is for the unit type.
This commit simplifies things by removing the generic parameter and
replacing it with an `Option`.
