Rollup merge of #101520 - oli-obk:transmute_lifetimes, r=compiler-errors 
Allow transmutes between the same types after erasing lifetimes

r? ````@compiler-errors````  on the impl

fixes #101081

See discussion in the issue and at https://rust-lang.zulipchat.com/#narrow/stream/326866-t-types.2Fnominated/topic/.23101081.3A.20Regression.20transmuting.20.60RwLockReadGuard.3CT.3A.20.3FSized.3E.E2.80.A6

I think this may need lang team signoff as its implications may go beyond the jurisdiction of T-types

I'll write up a proper summary later

bba9785dd7 Auto merge of #100720 - camsteffen:representable, r=cjgillot 
Rewrite representability

 * Improve placement of `Box` in the suggestion
 * Multiple items in a cycle emit 1 error instead of an error for each item in the cycle
 * Introduce `representability` query to avoid traversing an item every time it is used.
 * Also introduce `params_in_repr` query to avoid traversing generic items every time it is used.

a688a0305f Auto merge of #99505 - joboet:futex_once, r=thomcc 
std: use futex in `Once`

Now that we have efficient locks, let's optimize the rest of `sync` as well. This PR adds a futex-based implementation for `Once`, which drastically simplifies the implementation compared to the generic version, which is provided as fallback for platforms without futex (Windows only supports them on newer versions, so it uses the fallback for now).

Instead of storing a linked list of waiters, the new implementation adds another state (`QUEUED`), which is set when there are waiting threads. These now use `futex_wait` on that state and are woken by the running thread when it finishes and notices the `QUEUED` state, thereby avoiding unnecessary calls to `futex_wake_all`.

fc3d7eb91d don't ICE when normalizing closure input tys 
`normalize_and_add_constraints` doesn't add entries in `universe_causes`
when creating new universes, causing an ICE. Remove it!

Add spans to track normalization constraints.

Fix couple places where `universe_causes` is not updated correctly to
track newly added universes.

38743ec07d rustdoc: remove no-op CSS .rightside { position: initial } 
This CSS, added in 34bd2b845b3acd84c5a9bddae3ff8081c19ec5e9, overrode CSS
that was applied to the `.since` class:

34bd2b845b/src/librustdoc/html/static/rustdoc.css (L782-L795)

The absolute positioning for `.since` was abandoned in favor of always
floating it, so this is no longer needed:

8b0c05d9ad Auto merge of #102091 - RalfJung:const_err, r=oli-obk 
make const_err a hard error

This lint has been deny-by-default with future incompat wording since [Rust 1.51](https://github.com/rust-lang/rust/pull/80394) and the stable release of this week starts showing it in cargo's future compat reports. I can't wait to finally get rid of at least some of the mess in our const-err-reporting-code. ;)
