Fix UnsafeCell Documentation Spelling Error

This fixes the spelling of "deallocated" (instead of the original "deallocted") In the `cell.rs` source file. Honestly probably not worth the time to evaluate, but since it doesn't involve any code change, I figure why not?

Rollup merge of #106187 - ChayimFriedman2:patch-4, r=compiler-errors
Update the documentation of `Vec` to use `extend(array)` instead of `extend(array.iter().copied())`

Another option is to use `extend_from_slice()` (that may be faster), but I find this approach cleaner.

Rollup merge of #103718 - matklad:infer-lazy, r=dtolnay
More inference-friendly API for lazy

The signature for new was

```
fn new<F>(f: F) -> Lazy<T, F>
```

Notably, with `F` unconstrained, `T` can be literally anything, and just `let _ = Lazy::new(|| 92)` would not typecheck.

This historiacally was a necessity -- `new` is a `const` function, it couldn't have any bounds. Today though, we can move `new` under the `F: FnOnce() -> T` bound, which gives the compiler enough data to infer the type of T from closure.

Add env variables and cwd to the shell-like debug output.

Also use the alternate syntax to display a more verbose display, while not showing internal fields and hiding fields when they have their default value.

8dfb339541 Auto merge of #105997 - RalfJung:immediate-abort, r=eholk
abort immediately on bad mem::zeroed/uninit

Now that we have non-unwinding panics, let's use them for these assertions. This re-establishes the property that `mem::uninitialized` and `mem::zeroed` will never unwind -- the earlier approach of causing panics here sometimes led to hard-to-debug segfaults when the surrounding code was not able to cope with the unexpected unwinding.

Cc `@bjorn3` I did not touch cranelift but I assume it needs a similar patch. However it has a `codegen_panic` abstraction that I did not want to touch since I didn't know how else it is used.

Rename `assert_uninit_valid` intrinsic

It's not about "uninit" anymore but about "filling with 0x01 bytes" so the name should at least try to reflect that.

This is actually not fully correct though, as it does still panic for all uninit with `-Zstrict-init-checks`. I'm not sure what the best way is to deal with that not causing confusion. I guess we could just remove the flag? I don't think having it makes a lot of sense anymore with the direction that we have chose to go. It could be relevant again if #100423 lands so removing it may be a bit over eager.

fs: Fix #50619 (again) and add a regression test

Bug #50619 was fixed by adding an end_of_stream flag in #50630.
Unfortunately, that fix only applied to the readdir_r() path.  When I
switched Linux to use readdir() in #92778, I inadvertently reintroduced
the bug on that platform.  Other platforms that had always used
readdir() were presumably never fixed.

This patch enables end_of_stream for all platforms, and adds a
Linux-specific regression test that should hopefully prevent the bug
from being reintroduced again.

Rollup merge of #105458 - Ayush1325:blocking_spawn, r=Mark-Simulacrum
Allow blocking `Command::output`

### Problem
Currently, `Command::output` is internally implemented using `Command::spawn`. This is problematic because some targets (like UEFI) do not actually support multitasking and thus block while the program is executing. This coupling does not make much sense as `Command::output` is supposed to block until the execution is complete anyway and thus does not need to rely on a non-blocking `Child` or any other intermediate.

### Solution
This PR moves the implementation of `Command::output` to `std::sys`. This means targets can choose to implement only `Command::output` without having to implement `Command::spawn`.

### Additional Information

This was originally conceived when working on https://github.com/rust-lang/rust/pull/100316. Currently, the only target I know about that will benefit from this change is UEFI.

This PR can also be used to implement more efficient `Command::output` since the intermediate `Process` is not actually needed anymore, but that is outside the scope of this PR.

Since this is not a public API change, I'm not sure if an RFC is needed or not.

Implement DerefMut for PathBuf

Without this, there's no way to get a `&mut Path` from `PathBuf` without
going through `into_boxed_path`. This is relevant now that #105002 adds
`PathBuf::as_mut_os_string` and `Path::as_mut_os_str`.

doc: Fix a few small issues

Hey, while reading through the (awesome) stdlib docs, I found a few minor typos.

* A few typos around generic types (`;` vs `,`)
* Use inline code formatting for code fragments
* One instance of wrong wording

Custom MIR: Many more improvements

Commits are each atomic changes, best reviewed one at a time, with the exception that the last commit includes all the documentation.

### First commit

Unsafetyck was not correctly disabled before for `dialect = "built"` custom MIR. This is fixed and a regression test is added.

### Second commit

Implements `Discriminant`, `SetDiscriminant`, and `SwitchInt`.

### Third commit

Implements indexing, field, and variant projections.

### Fourth commit

Documents the previous commits and everything else.

There is some amount of weirdness here due to having to beat Rust syntax into cooperating with MIR concepts, but it hopefully should not be too much. All of it is documented.

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.

ba4dd464f5 fs: Fix #50619 (again) and add a regression test
Bug #50619 was fixed by adding an end_of_stream flag in #50630.
Unfortunately, that fix only applied to the readdir_r() path.  When I
switched Linux to use readdir() in #92778, I inadvertently reintroduced
the bug on that platform.  Other platforms that had always used
readdir() were presumably never fixed.

This patch enables end_of_stream for all platforms, and adds a
Linux-specific regression test that should hopefully prevent the bug
from being reintroduced again.

Rollup merge of #101648 - Timmmm:home_dir_docs, r=joshtriplett
Better documentation for env::home_dir()'s broken behaviour

This improves the documentation to say *why* it was deprecated. The reason was because it reads `HOME` on Windows which is meaningless there. Note that the PR that deprecated it stated that returning an empty string if `HOME` is set to an empty string was a problem, however I can find no evidence that this is the case. `cd` handles it fine whereas if `HOME` is unset it gives an explicit `HOME not set` error.

* Original deprecation reason: https://internals.rust-lang.org/t/deprecate-or-break-fix-std-env-home-dir/7315
* Original deprecation PR: https://github.com/rust-lang/rust/pull/51656
