ci: move /var/lib/docker to /mnt on GHA
There are some builders that are running out of disk space while
building the Docker images, such as arm-android. This moves and symlinks
/var/lib/docker to the /mnt partition on Linux GHA.

Remove marker comments in libstd/lib.rs macro imports
These comments were probably moved around when rustfmt was introduced. They don't correctly denote what they were intended for, so I propose we remove them instead. Thanks!

Stop importing the float modules in documentation
Follow up to #69860. I realized I had not searched for and fixed this for the float values. So with this PR they also use the associated constants instead of the module level constants.
For the documentation where it also was using the `consts` submodule I opted to change it to import that directly. This becomes more in line with how other docs that use the `consts` submodule looks. And it also makes it so there are not two `f32` or `f64` things in the current namespace (both the module and the primitive type) and then hopefully confusing documentation readers less.

Match options directly in the Fuse implementation
Rather than using `as_ref()`, `as_mut()`, and `?`, we can use `match` directly to save a lot of generated code. This was mentioned as a possibility in https://github.com/rust-lang/rust/pull/70366#issuecomment-603462546, and I found that it had a very large impact on #70332 using `Fuse` within `Chain`. Let's evaluate this change on its own first.
Rollup merge of #70665 - petrochenkov:linkargs, r=nagisa
Do not lose or reorder user-provided linker arguments
Linker arguments are potentially order-dependent, so the order in which `-C link-arg` and `-C link-args` options are passed to `rustc` should be preserved when they are passed further to the linker.
Also, multiple `-C link-args` options are now appended to each other rather than overwrite each other.
In other words, `-C link-arg=a -C link-args="b c" -C link-args="d e" -C link-arg=f` is now passed as `"a" "b" "c" "d" "e" "f"` and not as `"d" "e" "a" "f"`.

Rollup merge of #70812 - rossmacarthur:fix/unit-called-nil, r=LukasKalbertodt
Do not use "nil" to refer to `()`
"nil" is not used in the [book](https://doc.rust-lang.org/book) or in the [standard library](https://doc.rust-lang.org/std) anywhere else. Because "nil" is often used in programming languages to refer to "None" or "null" I think it could be a little confusing for newcomers to see this type referred to as "nil".
Rollup merge of #70777 - faern:use-assoc-int-consts2, r=dtolnay
Don't import integer and float modules, use assoc consts
Stop importing the standard library integer and float modules to reach the `MIN`, `MAX` and other constants. They are available directly on the primitive types now.
This PR is a follow up of #69860 which made sure we use the new constants in documentation.
This type of change touches a lot of files, and previously all my assoc int consts PRs had collisions and were accepted only after a long delay. So I'd prefer to do it in smaller steps now. Just removing these imports seem like a good next step.

docs: make the description of Result::map_or more clear
The documentation of [`Result::map_or`](https://doc.rust-lang.org/std/result/enum.Result.html#method.map_or) is very unclear and confusing, probably because it was copied straight from [`Option::map_or`](https://doc.rust-lang.org/std/option/enum.Option.html#method.map_or) and someone forgot to adapt it for Result.
Rollup merge of #70558 - RalfJung:vec-extend-aliasing, r=Amanieu
Fix some aliasing issues in Vec
`Vec::extend` and `Vec::truncate` invalidated references into the vector even without reallocation, because they (implicitly) created a mutable reference covering the *entire* initialized part of the vector.
Fixes https://github.com/rust-lang/rust/issues/70301
I verified the fix by adding some new tests here that I ran in Miri.
