Fix typo in Default trait docs: Provides -> Provide
An earlier commit (99ed06e) accidentally changed this paragraph from the original, imperative `Provide` to the present tense `Provides`. The latter is indeed the standard for Rustdoc comments relating to a function or method, but this snippet is introducing the `Default` trait in general terms and not talking about any particular function. I believe this change was likely made in error and should be reverted.
Dogfood or_patterns in the standard library
We can start using `or_patterns` in the standard library as a step toward stabilization.

reword Miri validity errors: undefined -> uninitialized
I don't think we say "undefined value" or anything like that anywhere in the docs or so, but we do use the term "uninitialized memory", so I think we should do the same here.
Longer-term, I think we should also internally rename "undef" to "uninit".

Hides default fns inside Fuse impl to avoid exposing it to any crate
Fixes#70796
@cuviper I've added some default, private traits to do the job for us. If required, I can expose them to a specific visibility if you want to call these functions for #70332

Minor fixes to doc comments of 'VecDeque'
1. Changed descriptions of `fn get` & `fn get_mut`.
Since both of these functions are returning references, and not the owned value, I thought the doc comments could be fixed to be consistent with doc comments of `fn front` & `fn front_mut`.
2. Other changes are minor fixes or additions for clarification.
Thank you for taking a look :)

Don't use the HirId to NodeId map in MIR
Another step towards not having to build a `HirId` to `NodeId` map other than for doc and RLS purposes.
We are currently sorting `unsafe` blocks by `NodeId` in `check_unsafety`; change it to sorting by `Span` instead; this passes the tests, but better ideas are welcome.
In addition, simplify the split between the used and unused `unsafe` blocks for readability and less sorting.

remove an impossible branch from check_consts
All function calleess are either `FnPtr` or `FnDef`, so we can remove the alternative from check_consts and just make it ICE instead.
Remove a stack frame from .await calls
The stack frames when `.await`ing one async fn from another currently look like this:
```
12: foo:🅱️:{{closure}}
at src/main.rs:2
13: <core::future::from_generator::GenFuture<T> as core::future::future::Future>::poll
at /home/sfackler/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/future/mod.rs:66
14: core::future::poll_with_context
at /home/sfackler/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/future/mod.rs:84
15: foo:🅰️:{{closure}}
at src/main.rs:6
```
Since the move away from using TLS to pass the Context around, it's now easy to remove frame 14 by removing poll_with_context in favor of calling Future::poll directly. This still leaves the `GenFuture` frame, but that seems significantly harder to deal with.
It also improves diagnostics a bit since they no longer talk about the private poll_with_context function.

Add illumos triple
This fixesrust-lang/rust#55553 and adds support for `illumos` as a `target_os` on `x86_64`. In addition to the compile spec and libstd additions, several library dependencies have been bumped in order to permit working builds of cargo and rustup for the new target.
Work originally started by @jasonbking, with subsequent additions by @pfmooney and @jclulow.
Improve rustdoc source code a bit
Very small clean up. I realized that there were too many nested conditions whereas we could just use `and_then`.
