The wrapper is installed as `ld` and `ld64` in the `lib\rustlib\<host_target>\bin\gcc-ld`
directory and its sole purpose is to invoke `rust-lld` in the parent directory with
the correct flavor.

Fix Windows LLVM issue.
GitHub image 20210928.2 added LLVM 12.0.1 to the stock image. However, the `lldb` executable doesn't work, it fails with:
> C:/Program Files/LLVM/bin/lldb.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
We probably don't want to start testing LLDB on windows anyways (at least not without intent).
The hacky solution for now is to just delete the system LLVM.
The backport of #89277 needed adjustment due to another
PR (#87915 - Use smaller spans for some structured suggestions)
causing the test to have a slightly different span.
Update Let's Encrypt ROOT CA certificate in dist-(i686|x86_64)-linux docker images
The DST Root CA X3 used by Let's Encrypt has expired ([Let's Encrypt announcement](https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/)). This patch installs the new root certificate (ISRG Root X1) and disables the old one. Disabling the old one is necessary because otherwise curl still fails to download from servers with Let's Encrypt certs even though they are cross-signed.
Fixes#89484.
Don't normalize opaque types with escaping late-bound regions
Fixes#88862
Turns out, this has some really bad perf implications in large types (issue #88862). While we technically can handle them fine, it doesn't change test output either way. For now, revert with an added benchmark. Future attempts to change this back will have to consider perf.
Needs a perf run once https://github.com/rust-lang/rustc-perf/pull/1033 is merged

Use the correct edition for syntax highlighting doctests
Previously it would unconditionally use edition 2015, which was incorrect.
Helps with https://github.com/rust-lang/rust/issues/89135 in that you can now override the doctest to be 2018 edition instead of being forced to fix the error. This doesn't resolve any of the deeper problems that rustdoc disagrees with most rust users on what a code block is.

[rfc 2229] Drop fully captured upvars in the same order as the regular drop code
Currently, with the new 2021 edition, if a closure captures all of the
fields of an upvar, we'll drop those fields in the order they are used
within the closure instead of the normal drop order (the definition
order of the fields in the type).
This changes that so we sort the captured fields by the definition order
which causes them to drop in that same order as well.
Fixesrust-lang/project-rfc-2229#42

Temporarily rename int_roundings functions to avoid conflicts
These functions are unstable, but because they're inherent they still
introduce conflicts with stable trait functions in crates. Temporarily
rename them to fix these conflicts, until we can resolve those conflicts
in a better way.
Don't use projection cache or candidate cache in intercrate mode
Fixes#88969
It appears that *just* disabling the evaluation cache (in #88994)
leads to other issues involving intercrate mode caching. I suspect
that since we now always end up performing the full evaluation
in intercrate mode, we end up 'polluting' the candidate and projection
caches with results that depend on being in intercrate mode in some way.
Previously, we might have hit a cached evaluation (stored during
non-intercrate mode), and skipped doing this extra work in
intercrate mode.
The whole situation with intercrate mode caching is turning into
a mess. Ideally, we would remove intercrate mode entirely - however,
this might require waiting on Chalk.
Fix linting when trailing macro expands to a trailing semi
When a macro is used in the trailing expression position of a block
(e.g. `fn foo() { my_macro!() }`), we currently parse it as an
expression, rather than a statement. As a result, we ended up
using the `NodeId` of the containing statement as our `lint_node_id`,
even though we don't normally do this for macro calls.
If such a macro expands to an expression with a `#[cfg]` attribute,
then the trailing statement can get removed entirely. This lead to
an ICE, since we were usng the `NodeId` of the expression to emit
a lint.
Ths commit makes us skip updating `lint_node_id` when handling
a macro in trailing expression position. This will cause us to
lint at the closest parent of the macro call.
Disable the evaluation cache when in intercrate mode
It's possible to use the same `InferCtxt` with both
an intercrate and non-intercrate `SelectionContext`. However,
the local (inferctxt) evaluation cache is not aware of this
distinction, so this kind of `InferCtxt` re-use will pollute
the cache wth bad results.
This commit avoids the issue by disabling the evaluation cache
entirely during intercrate mode.
Disable RemoveZsts in generators to avoid query cycles
Querying layout of a generator requires its optimized MIR. Thus
computing layout during MIR optimization of a generator might create a
query cycle. Disable RemoveZsts in generators to avoid the issue
(similar approach is used in ConstProp transform already).
Fixes#88972.
Fix WinUWP std compilation errors due to I/O safety
I/O safety for Windows has landed in #87329. However, it does not cover UWP specific parts and prevents all UWP targets from building. See https://github.com/YtFlow/Maple/issues/18. This PR fixes these compile errors when building std for UWP targets.
[beta] backports
- rustdoc: Fix ICE with `doc(hidden)` on tuple variant fields #88639

- Add a regression test for #88649#88691
- Revert anon union parsing #88775
- Disable validate_maintainers. #88977
Also drop stage0 rustfmt, because that's only supposed to be used on master.

This reverts commit 059b68dd67.
Note that this was manually adjusted to retain some of the refactoring
introduced by commit 059b68dd67, so that it could
likewise retain the correction introduced in commit
5b4bc05fa5
(cherry picked from commit 91feb76d13)
Each pattern in a match arm has its own copy of the match guard in MIR,
with its own temporary, so it has to be dropped before the the guards
are joined to the single copy of the arm.

The arguments to `span_suggestion` were in the wrong order, so the error
looked like this:
error[E0783]: trait objects without an explicit `dyn` are deprecated
--> src/test/ui/editions/dyn-trait-sugg-2021.rs:10:5
|
10 | Foo::hi(123);
| ^^^ help: <dyn Foo>: `use `dyn``
Now the error looks like this, as expected:
error[E0783]: trait objects without an explicit `dyn` are deprecated
--> src/test/ui/editions/dyn-trait-sugg-2021.rs:10:5
|
10 | Foo::hi(123);
| ^^^ help: use `dyn`: `<dyn Foo>`
This issue was only present in the 2021 error; the 2018 lint was
correct.
