[beta] Bump LLVM to a upstream 12.0 release
Currently the `beta` branch utilizes a release candidate of LLVM 12.0. Since then a large number of issues have been fixed upstream, including those that are known to affect Rust code.
It would be unfortunate if we released a stable Rust with all of those issues when we have the fixes in the actual LLVM release and/or our backports of commits that didn't make the release cut on top of it.

Upgrade `expat` dependency in riscv64 to newer version.
The old version was renamed to `expat-2.2.6-RENAMED-VULNERABLE-PLEASE-USE-2.3.0-INSTEAD`. :)

Update LLVM to bring in SIMD updates for WebAssembly
This is a continuation of https://github.com/rust-lang/llvm-project/pull/96

intrinsics on WebAssembly to the latest version of the specification.

Mark early otherwise optimization unsound
r? `@oli-obk`
cc `@tmiasko`
Related to #78496 and #82905
Should I also bump this one to level 3 or 4 or given that is unsound it doesn't matter?.
Probably need to adjust some tests.

Only build help popup when it's really needed
When working on https://github.com/rust-lang/rust/pull/79985, I realized that the help popup was built even when it wasn't needed. This PR only makes the help popup to be built when required.

Replace closures_captures and upvar_capture with closure_min_captures
Removed all uses of closures_captures and upvar_capture and refactored code to work with closure_min_captures. This also involved removing functions that were no longer needed like the bridge.
Closes https://github.com/rust-lang/project-rfc-2229/issues/18

Upgrade memmap to memmap2
memmap is no longer maintained. memmap2 is a fork that is still maintained. https://rustsec.org/advisories/RUSTSEC-2020-0077.html
The remaining use of memmap is through measureme.

Extend `proc_macro_back_compat` lint to `actix-web`
Unlike the other cases of this lint, there's no simple way to detect if
an old version of the relevant crate (`syn`) is in use. The `actix-web`
crate only depends on `pin-project` v1.0.0, so checking the version of
`actix-web` does not guarantee that a new enough version of
`pin-project` (and therefore `syn`) is in use.
Instead, we rely on the fact that virtually all of the regressed crates
are pinned to a pre-1.0 version of `pin-project`. When this is the case,
bumping the `actix-web` dependency will pull in the *latest* version of
`pin-project`, which has an explicit dependency on a newer v dependency
on a newer version of `syn`.
The lint message tells users to update `actix-web`, since that's what
they're most likely to have control over. We could potentially tell them
to run `cargo update -p syn`, but I think it's more straightforward to
suggest an explicit change to the `Cargo.toml`
The `actori-web` fork had its last commit over a year ago, and appears
to just be a renamed fork of `actix-web`. Therefore, I've removed the
`actori-web` check entirely - any crates that actually get broken can
simply update `syn` themselves.

rustdoc: allow list syntax for #[doc(alias)] attributes
Fixes https://github.com/rust-lang/rust/issues/81205.
It now allows to have:
```rust
#[doc(alias = "x")]
// and:
#[doc(alias("y", "z"))]
```

Attempt to gather similar stats as rusage on Windows
A follow up to #82532. This is a bit hacked in because I think we need to discuss this before merging, but this is an attempt to gather similar metrics as `libc::rusage` on Windows.
Some comments on differences:
* Currently, we're passing `RUSAGE_CHILDREN` to `rusage` which collects statistics on all children that have been waited on and terminated. I believe this is currently just the invocation of the real `rustc` that the shim is wrapping. Does `rustc` itself spawn children processes? The windows version gets the child processes handle when spawning it, and uses that to collect the statistics. For maxrss, `rusage` will return "the resident set size of the largest child, not the maximum resident set size of the process tree.", the Windows version will only collect statistics on the wrapped `rustc` child process directly even if some theoretical sub process has a larger memory footprint.
* There might be subtle differences between `rusage`'s "resident set" and Window's "working set". The "working set" and "resident set" should both be the number of pages that are in memory and which would not cause a page fault when accessed.
* I'm not yet sure how best to get the same information that `ru_minflt`, `ru_inblock`, `ru_oublock`, `ru_nivcsw ` and `ru_nvcsw` provide.

feat: Update hashbrown to instantiate less llvm IR
Includes https://github.com/rust-lang/hashbrown/pull/204 and https://github.com/rust-lang/hashbrown/pull/205 (not yet merged) which both serve to reduce the amount of IR generated for hashmaps.
