enable align_to tests in Miri

With https://github.com/rust-lang/miri/issues/1074 resolved, we can enable these tests in Miri.

I also tweaked the test sized to get reasonable execution times with decent test coverage.

Rollup merge of #75324 - ericseppanen:master, r=JohnTitor
clarify documentation of remove_dir errors

remove_dir will error if the path doesn't exist or isn't a directory.

It's useful to clarify that this is "remove dir or fail" not "remove dir
if it exists".

I don't think this belongs in the title. "Removes an existing, empty
directory" is strangely worded-- there's no such thing as a non-existing
directory.  Better to just say explicitly it will return an error.

d9d4d39612 Auto merge of #73565 - matthewjasper:core-min-spec, r=nagisa
Use min_specialization in libcore

Getting `TrustedRandomAccess` to work is the main interesting thing here.

- `get_unchecked` is now an unstable, hidden method on `Iterator`
- The contract for `TrustedRandomAccess` is made clearer in documentation
- Fixed a bug where `Debug` would create aliasing references when using the specialized zip impl
- Added tests for the side effects of `next_back` and `nth`.

Remove `#[cfg(miri)]` from OnceCell tests

They were carried over from once_cell crate, but they are not entirely

11a44adc6f Auto merge of #75600 - nagisa:improve_align_offset, r=KodrAus
Improve codegen for `align_offset`

In this PR the `align_offset` implementation is changed/improved to produce better code in certain scenarios such as when pointer type is has a stride of 1 or when building for low optimisation levels.

While these changes do not achieve the "ideal" codegen referenced in #75579, it gets significantly closer to it. I’m not actually sure if the codegen can actually be much better with this function returning the offset, rather than the aligned pointer.

See the descriptions for separate commits for further information.

docs(marker/copy): provide example for `&T` being `Copy`

### Edited 2020-08-16 (most recent)
In the current documentation about the `Copy` marker trait, there is a section
with examples of structs that can implement `Copy`. Currently there is no example for
showing that shared references (`&T`) are also `Copy`.
It is worth to have a dedicated example for `&T` being `Copy`, because shared
references are an integral part of the language and it being `Copy` is not as
intuitive as other types that share this behaviour like `i32` or `bool`.

The example picks up on the previous non-`Copy` struct and shows that
structs can be `Copy`, even when they hold a shared reference to a non-`Copy` type.

-----------------------------------------
### Edited 2020-08-02, 3:28 p.m.
I've just realized that it says "in addition to the **implementors listed below**", which makes this PR kind of "wrong", because `&T` is indeed in the "implementors listed below".
Maybe we can instead show an example with `&T` in the [When can my type be Copy](https://doc.rust-lang.org/std/marker/trait.Copy.html#when-can-my-type-be-copy) section.

What I really want to achieve is that it becomes more obvious that `&T` is also `Copy`, because, I think, it is very valuable to know and it wasn't obvious for me, until I read something about it in a forum post.

What do you think? I would create another PR for that.
**Please feel free to close this PR.**

-----------------------------------
### Original post
In the current documentation about the `Copy` marker trait, there is a section
about "additional implementors", which list additional implementors of the `Copy` trait.
The fact that shared references are also `Copy` is mixed with another point,
which makes it hard to recognize and make it seem not as important.

This clarifies the fact that shared references are also `Copy`, by mentioning it as a
separate item in the list of "additional implementors".

c03c213daf Auto merge of #75677 - cuviper:shrink-towel, r=Mark-Simulacrum
Don't panic in Vec::shrink_to_fit

We can help the compiler see that `Vec::shrink_to_fit` will never reach the panic case in `RawVec::shrink_to_fit`, just by guarding the call only for cases where the capacity is strictly greater. A capacity less than the length is only possible through an unsafe call to `set_len`, which would break the `Vec` invariants, so `shrink_to_fit` can just ignore that.

This removes the panicking code from the examples in both #71861 and #75636.

Reference lang items during AST lowering

Fixes #60607 and fixes #61019.

This PR introduces `QPath::LangItem` to the HIR and uses it in AST lowering instead of constructing a `hir::Path` from a slice of symbols:

- Credit for much of this work goes to @matthewjasper, I basically just [rebased their earlier work](a227c706b7 (diff-c0f791ead38d2d02916faaad0f56f41d)).
- ~~Changes to Clippy might not be correct, they compile but attempting to run tests through `./x.py` produced failures which appeared spurious, so I didn't run any clippy tests.~~
- Changes to save analysis might not be correct - tests pass but I don't have a lot of confidence in those changes being correct.
- I've used `GenericBounds::LangItemTrait` rather than changing `PolyTraitRef`, as suggested by @matthewjasper [in this comment](a227c706b7 (r40107992)) but I'd prefer that be left for a follow-up.
- I've split things into smaller commits fairly arbitrarily to make the diff easier to review, each commit should compile but might not pass tests until the final commit.
