Auto merge of #90291 - geeklint:loosen_weak_debug_bound, r=dtolnay
Loosen the bound on the Debug implementation of Weak.
Both `rc::Weak<T>` and `sync::Weak<T>` currently require `T: Debug` in their own `Debug` implementations, but they don't currently use it; they only ever print a fixed string.
A general implementation of Debug for Weak that actually attempts to upgrade and rely on the contents is unlikely in the future because it may have unbounded recursion in the presence of reference cycles, which Weak is commonly used in. (This was the justification for why the current implementation [was implemented the way it is](https://github.com/rust-lang/rust/pull/19388/commits/f0976e2cf3f6b0027f118b791e0888b29fbb41a7)).
When I brought it up [on the forum](https://internals.rust-lang.org/t/could-the-bound-on-weak-debug-be-relaxed/15504), it was suggested that, even if an implementation is specialized in the future that relies on the data stored within the Weak, it would likely rely on specialization anyway, and could therefore easily specialize on the Debug bound as well.

Auto merge of #104658 - thomcc:rand-update-and-usable-no_std, r=Mark-Simulacrum
Update `rand` in the stdlib tests, and remove the `getrandom` feature from it.
The main goal is actually removing `getrandom`, so that eventually we can allow running the stdlib test suite on tier3 targets which don't have `getrandom` support. Currently those targets can only run the subset of stdlib tests that exist in uitests, and (generally speaking), we prefer not to test libstd functionality in uitests, which came up recently in https://github.com/rust-lang/rust/pull/104095 and https://github.com/rust-lang/rust/pull/104185. Additionally, the fact that we can't update `rand`/`getrandom` means we're stuck with the old set of tier3 targets, so can't test new ones.
~~Anyway, I haven't checked that this actually does allow use on tier3 targets (I think it does not, as some work is needed in stdlib submodules) but it moves us slightly closer to this, and seems to allow at least finally updating our `rand` dep, which definitely improves the status quo.~~ Checked and works now.
For the most part, our tests and benchmarks are fine using hard-coded seeds. A couple tests seem to fail with this (stuff manipulating the environment expecting no collisions, for example), or become pointless (all inputs to a function become equivalent). In these cases I've done a (gross) dance (ab)using `RandomState` and `Location::caller()` for some extra "entropy".
Trying to share that code seems *way* more painful than it's worth given that the duplication is a 7-line function, even if the lines are quite gross. (Keeping in mind that sharing it would require adding `rand` as a non-dev dep to std, and exposing a type from it publicly, all of which sounds truly awful, even if done behind a perma-unstable feature).
See also some previous attempts:
- https://github.com/rust-lang/rust/pull/86963 (in particular https://github.com/rust-lang/rust/pull/86963#issuecomment-885438936 which explains why this is non-trivial)

- https://github.com/rust-lang/rust/pull/96626#issuecomment-1114562857 (I tried in that PR at the same time, but settled for just removing the usage of `thread_rng()` from the benchmarks, since that was the main goal).

Suggest adding named lifetime when the return contains value borrowed from more than one lifetimes of function inputs
fix for #105227.
The problem: The suggestion of adding an explicit `'_` lifetime bound is **incorrect** when the function's return type contains a value which could be borrowed from more than one lifetimes of the function's inputs. Instead, a named lifetime parameter can be introduced in such a case.
The solution: Checking the number of elided lifetimes in the function signature. If more than one lifetimes found in the function inputs when the suggestion of adding explicit `'_` lifetime, change it to using named lifetime parameter `'a` instead.

Fix error-index redirect to work with the back button.
This fixes the redirect page at https://doc.rust-lang.org/error-index.html so that it works with the browser's back-button. The solution is to use `window.location.replace()`, which avoids adding the page to the browser history stack.
This also cleans up the code a little bit, since it looks like it was written with different assumptions (maybe before f5857d5c5e1d2fde302f330d11c5cdea8005eb2a). I don't think there is a need to have a redirect at https://doc.rust-lang.org/error_codes/error-index.html since I don't think fragment-based links were ever used there.
I have tested with Firefox, Chrome, and Safari. Going to `/error-index.html` redirects without adding to the stack, and can use the back button. Additionally, `/error-index.html#E0005` redirects correctly to the error page.
Finally, there is an unrelated commit to remove the 404 hack. There is an official way of avoiding the generation of the 404 page with setting input-404 to an empty value.
