39b841dfe3 Auto merge of #79621 - usbalbin:constier_maybe_uninit, r=RalfJung 
Constier maybe uninit

I was playing around trying to make `[T; N]::zip()` in #79451 be `const fn`. One of the things I bumped into was `MaybeUninit::assume_init`. Is there any reason for the intrinsic `assert_inhabited<T>()` and therefore `MaybeUninit::assume_init` not being `const`?

---

I have as best as I could tried to follow the instruction in [library/core/src/intrinsics.rs](https://github.com/rust-lang/rust/blob/master/library/core/src/intrinsics.rs#L11). I have no idea what I am doing but it seems to compile after some slight changes after the copy paste. Is this anywhere near how this should be done?

Also any ideas for name of the feature gate? I guess `const_maybe_assume_init` is quite misleading since I have added some more methods. Should I add test? If so what should be tested?

26e4cf0fc7 Rollup merge of #79795 - matklad:unicode-private, r=cramertj 
Privatize some of libcore unicode_internals

My understanding is that these API are perma unstable, so it doesn't
make sense to pollute docs & IDE completion[1] with them.

Use more std:: instead of core:: in docs for consistency

``@rustbot`` label T-doc

Some cleanup work to use `std::` instead of `core::` in docs as much as possible. This helps with terminology and consistency, especially for newcomers from other languages that have often heard of `std` to describe the standard library but not of `core`.

Edit: I also added more intra doc links when I saw the opportunity.

b565fe241e Rollup merge of #79038 - CDirkx:move-ui-tests, r=dtolnay 
Change ui test that are run-pass and that do not test the compiler to library tests

Part of #76268, these are some of the relevant ui tests I found that can be replaced by library tests.

Note: this PR just moves the tests, I have not checked for any overlap between these tests and existing library tests. The only test I changed is `env_home_dir`, where I added code to restore the old home dir after testing.

All moved tests:
