backport: move new c abi abort behavior behind feature gate

This is a backport of PR #84158 to the beta branch.

The original T-compiler plan was to revert PR #76570 in its entirety, as was attempted in PR #84672. But the revert did not go smoothly (details below).

Therefore, we are backporting PR #84158 instead, which was our established backup plan if a revert did not go smoothly.

I have manually confirmed that this backport fixes the luajit issue described on issue #83541

<details>

<summary>Click for details as to why revert of PR #76570 did not go smoothly.</summary>

It turns out that Miri had been subsequently updated to reflect changes to `rustc_target` that landed in PR #76570. This meant that the attempt to land PR #84672 broke Miri builds.

Normally we allow tools to break when landing PR's (and just expect follow-up PR's to fix the tools), but we don't allow it for tools in the run-up to a release.

(We shouldn't be using that uniform policy for all tools. Miri should be allow to break during the week before a release; but currently we cannot express that, due to issue #74709.)

Therefore, its a lot of pain to try to revert PR #76570. And we're going with the backup plan.

Original commit message follows:

----

 *Background*

In #76570, new ABI strings including `C-unwind` were introduced. Their behavior is specified in RFC 2945 <sup>[1]</sup>.

However, it was reported in the #ffi-unwind stream of the Rust community Zulip that this had altered the way that `extern "C"` functions behaved even when the `c_unwind` feature gate was not active. <sup>[2]</sup>

 *Overview*

 This makes a small patch to `rustc_mir_build::build::should_abort_on_panic`, so that the same  behavior from before is in place when the `c_unwind` gate is not active.

`rustc_middle::ty::layout::fn_can_unwind` is not touched, as the visible behavior should not differ before/after #76570. <sup>[3]</sup>

[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.

Fix Self keyword doc URL conflict on case insensitive file systems (until definitely fixed on rustdoc)

This is just a hack to allow rustup to work on macOS and windows again to distribute std documentation (hopefully once https://github.com/rust-lang/rfcs/pull/3097 or an equivalent is merged).

Fixes https://github.com/rust-lang/rust/issues/80504. Prevents https://github.com/rust-lang/rust/issues/83154 and https://github.com/rust-lang/rustup/issues/2694 in future releases.

bors cd82e451a8 Auto merge of #83293 - osa1:82436_perf, r=varkor 
Revert performance-sensitive change in #82436

This change was done in #82436, as an "optimization". Unfortunately I
missed that this code is not always executed, because of the "continue"
in the conditional above it.

This commit should solve the perf regressions introduced by #82436 as I
think there isn't anything else that could affect runtime performance in
that PR. The `Pick` type grows only one word, which I doubt can cause up
to 8.8% increase in RSS in some of the benchmarks.

Could someone with the rights start a perf job please?
