Rollup merge of #78641 - the8472:buffered-copy, r=sfackler
Let io::copy reuse BufWriter buffers

This optimization will allow users to implicitly set the buffer size for io::copy by wrapping the writer into a `BufWriter` if the default block size is insufficient, which should fix #49921

Due to min_specialization limitations this approach only works with `BufWriter` but not for `BufReader<R>` since `R` is unconstrained and thus the necessary specialization on `R: Read` is not always applicable. Once specialization becomes more powerful this optimization could be extended to look at the reader and writer side and use whichever buffer is larger.

9607b5c6ac Auto merge of #80851 - m-ou-se:panic-2021, r=petrochenkov
Implement Rust 2021 panic

This implements the Rust 2021 versions of `panic!()`. See https://github.com/rust-lang/rust/issues/80162 and https://github.com/rust-lang/rfcs/pull/3007.

It does so by replacing `{std, core}::panic!()` by a bulitin macro that expands to either `$crate::panic::panic_2015!(..)` or `$crate::panic::panic_2021!(..)` depending on the edition of the caller.

This does not yet make std's panic an alias for core's panic on Rust 2021 as the RFC proposes. That will be a separate change: c5273bdfb2 That change is blocked on figuring out what to do with https://github.com/rust-lang/rust/issues/80846 first.

82010e86d3 rustdoc: Note why rustdoc::html::markdown is public
Almost all of the modules are crate-private, except for
`rustdoc::json::types`, which I believe is intended to be for public
use; and `rustdoc::html::markdown`, which is used externally by the
error-index generator and so has to be public.

Improve handling of spans around macro result parse errors
Fixes #81543

After we expand a macro, we try to parse the resulting tokens as a AST
node. This commit makes several improvements to how we handle spans when
an error occurs:

* Only ovewrite the original `Span` if it's a dummy span. This preserves
  a more-specific span if one is available.
* Use `self.prev_token` instead of `self.token` when emitting an error
  message after encountering EOF, since an EOF token always has a dummy
  span
* Make `SourceMap::next_point` leave dummy spans unused. A dummy span
  does not have a logical 'next point', since it's a zero-length span.
  Re-using the span span preserves its 'dummy-ness' for other checks

d5c221107e add Vec::extend_from_within method
Implement <https://github.com/rust-lang/rfcs/pull/2714>, changes from the RFC:
- Rename the method `append_from_within` => `extend_from_within`
- Loose :Copy bound => :Clone
- Specialize in case of :Copy

This commit also adds `Vec::split_at_spare` private method and use it to implement
`Vec::spare_capacity_mut` and `Vec::extend_from_within`. This method returns 2
slices - initialized elements (same as `&mut vec[..]`) and uninitialized but
allocated space (same as `vec.spare_capacity_mut()`).

3acd1a4f92 Fix calling convention for CRT startup
My PR #81478 used the wrong calling convention for a set of
functions that are called by the CRT. These functions need to use
`extern "C"`.

This would only affect x86, which is the only target (that I know of)
that has multiple calling conventions.

I added `allow(const_evaluatable_unchecked)`, but maybe we just don't want to add a test for this as the program is not really valid?

Don't link with --export-dynamic on wasm32-wasi

Remove --export-dynamic from the link arguments on the wasm32-wasi
target, as it emits spurious exports and increases code size.

Leave it in place for wasm32-unknown-unknown and
wasm32-unknown-emscripten. Even though it isn't a great solution
there, users are likely depending on its behavior there.

I thought there might be some issue with `Repeats(_, 0)`, but if you increase the items in the array it still ICEs. I'm not sure if this is the best fix but it does fix the given issue.

2229: Fix issues with move closures and mutability

This PR fixes two issues when feature `capture_disjoint_fields` is used.

1. Can't mutate using a mutable reference
2. Move closures try to move value out through a reference.

To do so, we
1. Compute the mutability of the capture and store it as part of the `CapturedPlace`  that is written in TypeckResults
2. Restrict capture precision. Note this is temporary for now, to allow the feature to be used with move closures and ByValue captures and might change depending on discussions with the lang team.
    - No Derefs are captured for ByValue captures, since that will result in value behind a reference getting moved.
    - No projections are applied to raw pointers since these require unsafe blocks. We capture
    them completely.

c5f3f9df3b Auto merge of #6603 - ThibsG:MatchOverlappingArm5986, r=flip1995
Do not lint when range is completely included into another one

This fix has been developed following this [comment](https://github.com/rust-lang/rust-clippy/issues/5986#issuecomment-703313548).
So this will be linted:
```
|----------|
        |-----------|
```
Now this won't be linted:
```
              |---|
|--------------------|
```
and this will still lint:
```
|--------|
|--------------|
```

Fixes: #5986

1fe1fa9122 Avoid building LLVM just for llvm-dwp
When the LLVM backend is disabled, the llvm-project submodule is not
checked out by default. This breaks the bootstrap test for cg_clif. As
cg_clif doesn't support split debuginfo anyway llvm-dwp is not
necessary. Other backends would likely not want to build LLVM just for
llvm-dwp either.
