Avoid allocations and copying in Vec::leak

The [`Vec::leak`] method (#62195) is currently implemented by calling `Vec::into_boxed_slice` and `Box::leak`.  This shrinks the vector before leaking it, which potentially causes a reallocation and copies the vector's contents.

By avoiding the conversion to `Box`, we can instead leak the vector without any expensive operations, just by returning a slice reference and forgetting the `Vec`.  Users who *want* to shrink the vector first can still do so by calling `shrink_to_fit` explicitly.

**Note:**  This could break code that uses `Box::from_raw` to “un-leak” the slice returned by `Vec::leak`.  However, the `Vec::leak` docs explicitly forbid this, so such code is already incorrect.

correctly. However, this assumed that the current substitution's span

move implicit `Sized` predicate to end of list

In `Bounds::predicates()`, move the implicit `Sized` predicate to the
end of the generated list. This means that if there is an explicit
`Sized` bound, it will be checked first, and any resulting
diagnostics will have a more useful span.

Fixes #85998, at least partially. ~~Based on #85979, but only the last 2 commits are new for this pull request.~~ (edit: rebased) A full fix would need to deal with where-clauses, and that seems difficult. Basically, predicates are being collected in multiple stages, and there are two places where implicit `Sized` predicates can be inserted: once for generic parameters, and once for where-clauses. I think this insertion is happening too early, and we should actually do it only at points where we collect all of the relevant trait bounds for a type parameter.

I could use some help interpreting the changes to the stderr output. It looks like reordering the predicates changed some diagnostics that don't obviously have anything to do with `Sized` bounds. Possibly some error reporting code is making assumptions about ordering of predicates? The diagnostics for src/test/ui/derives/derives-span-Hash-*.rs seem to have improved, no longer pointing at the type parameter identifier, but src/test/ui/type-alias-impl-trait/generic_duplicate_param_use9.rs became less verbose for some reason.

I also ran into an instance of #84970 while working on this, but I kind of expected that could happen, because I'm reordering predicates. I can open a separate issue on that if it would be helpful.

``@estebank`` this seems likely to conflict (slightly?) with your work on #85947; how would you like to resolve that?

Rollup merge of #89433 - arlosi:stdin-fix, r=joshtriplett

Fix ctrl-c causing reads of stdin to return empty on Windows.

Pressing ctrl+c (or ctrl+break) on Windows caused a blocking read of stdin to unblock and return empty, unlike other platforms which continue to block.

On ctrl-c, `ReadConsoleW` will return success, but also set `LastError` to `ERROR_OPERATION_ABORTED`.

This change detects this case, and re-tries the call to `ReadConsoleW`.

Add check that live_region is live in sanitize_promoted

This pull request fixes #88434 by adding a check in `sanitize_promoted` to ensure that only regions which are actually live are added to the `liveness_constraints` of the `BorrowCheckContext`.

To implement this change, I needed to add a method to `LivenessValues` which gets the elements contained by a region:

    /// Returns an iterator of all the elements contained by the region `r`
    crate fn get_elements(&self, row: N) -> impl Iterator<Item = Location> + '_

Then, inside `sanitize_promoted`, we check whether the iterator returned by this method is non-empty to ensure that the region is actually live at at least one location before adding that region to the `liveness_constraints` of the `BorrowCheckContext`.

This is my first pull request to the Rust repo, so any feedback on how I can improve this pull request or if there is a better way to fix this issue would be very appreciated.

## Changes

The following changes are made:

- We've removed prior mentions of "hardware threads" and instead centers the docs around "parallelism" as a resource available to a program.
- We now provide examples of when `available_parallelism` may return numbers that differ from the number of CPU cores in the host machine.
- We now mention that the amount of available parallelism may change over time.
- We make note of which platform components we don't take into account which more advanced users may want to take note of.
- The example has been updated, which should be a bit easier to use.
- We've added a docs alias to `num-cpus` which provides similar functionality to `available_parallelism`, and is one of the most popular crates on crates.io.
