rustdoc: remove no-op CSS `.scrape-example .src-line-numbers { margin: 0 }`
This is the default CSS for `<pre>` tags in `.code-wrapper` anyway, so this line does nothing.
rustdoc: remove unnecessary CSS `kbd { cursor: default }`
Added along with theme picker changes in https://github.com/rust-lang/rust/pull/47686/files#diff-7dc22a0530802d77c2f2ec9e834024a5657b6eab4055520fca46edc99a544413R1144, but no reason seems to have been given at the time for why this particular rule was added.
Removing this rule results in `<kbd>` elements getting an I-bar, while the rule causes them to use the "default" arrow, but since selecting the text in these elements works fine, the I-bar is not misleading.
Various cleanups to dest prop
This makes fixing the issues identified in #105577 easier. A couple changes
- Use an enum with names instead of a bool
- Only call `remove_candidates_if` from one place instead of two. Doing it from two places is far too fragile, since any divergence in the behavior between those callsites is likely to be unsound.
- Remove `is_constant`. Right now we only merge locals, so this doesn't do anything, and the logic would be wrong if it did.

Auto traits in `dyn Trait + Auto` are suggestable
Not sure why I had made the `IsSuggestableVisitor` have that rule to not consider `dyn Trait + Auto` to be suggestable.
It's possible that this was done because of the fact that we don't print the right parentheses for `&(dyn Trait + Auto)`, but that's a problem with printing these types in general that we probably have tracked somewhere else...
Ensure async trait impls are async (or otherwise return an opaque type)
As a workaround for the full `#[refine]` semantics not being implemented
yet, forbit returning a concrete future type like `Box<dyn Future>` or a
manually implemented Future.
`-> impl Future` is still permitted; while that can also cause
accidental refinement, that's behind a different feature gate
(`return_position_impl_trait_in_trait`) and that problem exists
regardless of whether the trait method is async, so will have to be
solved more generally.

Highlight conflicting param-env candidates, again
Un-reverts #98794 (i.e. reverts #99290).
The previous time I attempted to land this PR, it was because of an incremental issue (#99233). The repro instructions in the issue is no longer manifest the ICE -- I think it's because this ambiguity code was refactored (I think by `@lcnr)` to no longer store the ambiguities in the fulfillment error, but instead recompute them on the fly.
The main motivation for trying to re-land this is that it fixes#105131 by highlighting the root-cause of the issue, which is conflicting param-env candidates:
```
error[E0283]: type annotations needed: cannot satisfy `Self: Gen<'source>`

note: multiple `impl`s or `where` clauses satisfying `Self: Gen<'source>` found
--> $DIR/conflicting-bounds.rs:3:1

LL | pub trait Gen<'source> {

...
LL | Self: for<'s> Gen<'s, Output = T>;

error: aborting due to previous error

Fixes#105131.
Fixes (again) #98786
Sync rustc_codegen_cranelift
This time there are a bunch of bugfixes, some new llvm intrinsic implementations and refactorings to the build system in preparation for running cg_clif tests as part of `./x.py test`.

Add a test for #92481
The test was copied ad-hoc from #92481, but I can't get the test to pass, because of needing to get twice the same error on the last line of the source.
Closes#92481
Use more LFS functions.
On Linux, use mmap64, open64, openat64, and sendfile64 in place of their non-LFS counterparts.
This is relevant to #94173.
With these changes (together with rust-lang/backtrace-rs#501), the simple binaries I produce with rustc seem to have no non-LFS functions, so maybe #94173 is fixed. But I can't be sure if I've missed something and maybe some non-LFS functions could sneak in somehow.
