Add Vec::retain_mut

This is to continue the discussion started in #83218.

Original comment was:

> Take 2 of #34265, since I needed this today.

The reason I think why we should add `retain_mut` is for coherency and for discoverability. For example we have `chunks` and `chunks_mut` or `get` and `get_mut` or `iter` and `iter_mut`, etc. When looking for mutable `retain`, I would expect `retain_mut` to exist. It took me a while to find out about `drain_filter`. So even if it provides an API close to `drain_filter`, just for the discoverability, I think it's worth it.

Without this change, it is not possible to use `panic!` and similar (including `assert!`) in stable const contexts inside of stdlib. See #89542 for a real-world case that currently fails for this reason. This does _not_ affect any user code.

For example, this snippet currently fails to compile:

```rust
#[stable(feature = "foo", since = "1.0.0")]
#[rustc_const_stable(feature = "foo", since = "1.0.0")]
const fn foo() {
    assert!(false);
    assert!(false, "foo");
}
```

With the addition of `#[rustc_const_unstable]` to `core::panicking::panic`, the error no longer occurs. This snippet has been added verbatim in this PR as a UI test.

To avoid needing to add `#![feature(core_panic)]` to libcore, the two instances of direct calls to `core::panicking::panic` have been switched to use the `panic!` macro.

I am requesting prioritization because this is holding up other stabilizations such as #89542 (which is otherwise ready to merge and succeeds with this change)

Build musl dist artifacts with debuginfo enabled

Since our musl targets link to a version of musl we build and bundle
with the targets, if users need to debug into musl or generate
backtraces which contain parts of the musl library, they will be unable
to do so unless we enable and ship the debug info.

This patch changes our dist builds so they enabled debug info when
building musl. This patch also includes a fix for CFI detection in
musl's `configure` script which has been [posted upstream](https://www.openwall.com/lists/musl/2021/10/21/2).

The net effect of this is that we now ship debug info for musl in those
targets. This adds ~90kb to those artifacts but running `strip` on
binaries produced removes all of that. For a "hello world" Rust binary
on x86_64, the numbers are:

|                        | debug | release | release + strip |
|           -            |   -   |    -    |        -        |
| without musl debuginfo | 507kb |  495kb  |      410kb      |
| with musl debuginfo    | 595kb | 584kb | 410kb |

Once stripped, the final binaries are the same size (down to the byte).

Most arena-allocate types that impl `Drop` get their own `TypedArena`, but a

attribute of the `arena_types` macro. This change removes over 100 lines of

rustc_mir_build: reorder bindings

No functional changes intended.

I'm playing around with building compiler components using nightly rust
(2021-11-02) in a non-standard way. I encountered the following error while
trying to build rustc_mir_build:

```
error[E0597]: `wildcard` does not live long enough

     |     `wildcard` dropped here while still borrowed
     |     borrow might be used here, when `guard_candidate` is dropped and runs the destructor for type `Candidate<'_, '_>`

I believe this flags an issue that may become an error in the future.
Swapping the order of `wildcard` and `guard_candidate` resolves it.

Fixes incorrect handling of TraitRefs when emitting suggestions.

Closes #90804 , although there were more issues here that were hidden by the thing that caused this ICE.

Underlying problem was that substitutions were being thrown out, which not only leads to an ICE but also incorrect diagnostics. On top of that, in some cases the self types from the root obligations were being mixed in with those from derived obligations.

This makes a couple diagnostics arguable worse ("`B<C>` does not implement `Copy`" instead of "`C` does not implement `Copy`") but the worse diagnostics are at least still correct and that downside is in my opinion clearly outweighed by the benefits of fixing the ICE and unambiguously wrong diagnostics.

These are working well for *unsigned* types, so keep those, but for the the *signed* ones there are a bunch of questions about what the semantics and API should be.  For the main "helpers for big integer implementations" use, there's no need for the signed versions anyway.  There are plenty of other methods which exist for unsigned types but not signed ones, like `next_power_of_two`, so this isn't unusual.

stabilize format args capture

Works as expected, and there are widespread reports of success with it, as well as interest in it.

RFC: rust-lang/rfcs#2795
Tracking issue: https://github.com/rust-lang/rust/issues/67984

Addressing items from the tracking issue:

- We don't support capturing arguments from a non-literal format string like `format_args!(concat!(...))`. We could add that in a future enhancement, or we can decide that it isn't supported (as suggested in https://github.com/rust-lang/rust/issues/67984#issuecomment-801394736 ).
- I've updated the documentation.
- `panic!` now supports capture as well.
- There are potentially opportunities to further improve diagnostics for invalid usage, such as if it looks like the user tried to use an expression rather than a variable. However, such cases are all already caught and provide reasonable syntax errors now, and we can always provided even friendlier diagnostics in the future.

rustc_mir_build: reorder bindings

No functional changes intended.

I'm playing around with building compiler components using nightly rust
(2021-11-02) in a non-standard way. I encountered the following error while
trying to build rustc_mir_build:

```
error[E0597]: `wildcard` does not live long enough
    --> rust/src/nightly/compiler/rustc_mir_build/src/build/matches/mod.rs:1767:82

     |     -

     |     `wildcard` dropped here while still borrowed
     |     borrow might be used here, when `guard_candidate` is dropped and runs the destructor for type `Candidate<'_, '_>`
     |
     = note: values in a scope are dropped in the opposite order they are defined
```

I believe this flags an issue that may become an error in the future.
Swapping the order of `wildcard` and `guard_candidate` resolves it.

Auto merge of #90717 - kit-981:fix-ld64-flags, r=petrochenkov

Fix ld64 flags

- The `-exported_symbols_list` argument appears to be malformed for `ld64` (if you are not going through `clang`).
- The `-dynamiclib` argument isn't support for `ld64`. It should be guarded behind a compiler flag.

These problems are fixed by these changes. I have also refactored the way linker arguments are generated to be ld/compiler agnostic and therefore less error prone.

These changes are necessary to support cross-compilation to darwin targets.

Remove `DropArena`.

Most arena-allocate types that impl `Drop` get their own `TypedArena`, but a
few infrequently used ones share a `DropArena`. This sharing adds complexity
