Implement `confusable_idents` lint.
This collects all identifier symbols into `ParseSession` and examines them within the non-ascii-idents lint.
The skeleton generation part needs to be added to `unicode-security` crate. Will update this PR when the crate is updated.

EDIT: also included the `concat_idents` part.
Implement RFC 2523, `#[cfg(version(..))]`
Hi! This is my first contribution to rust, I hope I didn't miss anything. I tried to implement this feature so that `#[cfg(version(1.44.0))]` works but the parser was printing an error that I wasn't sure how to fix so I just opted for implementing `#[cfg(version("1.44.0"))]` (note the quotes).
Tracking issue: #64796
The extracted function can be used by the rest of bootstrap to detect if we've
already built an up-to-date LLVM (and so it's safe for us to either request it
or pretend it exists).

bootstrap: also apply unused-attributes hack without deny_warnings
This is a follow-up to https://github.com/rust-lang/rust/pull/70881 that also silences these warnings when deny_warnings is off. They otherwise spam my screen during development and make it hard to see actual warnings.

Miri: port error backtraces to std::backtrace
No need to pull in an external dependency if libstd already includes this feature (using the same dependency internally, but... still).

wf: handle "livelock" checking before reaching `WfPredicates::compute`.
For `wf::obligations`'s "livelock" handling, this PR shouldn't cause any behavioral changes, as the check moved to it should be equivalent to the old one in `WfPredicates::compute`.
However, it fixes#70168 by making *other* users of `WfPredicates::compute` (that is, `wf::predicate_obligations` and `compute`'s own upvar handling) correct for `ty::Infer`, in that they now get a `WellFormed(ty::Infer(_))` obligation instead of silently ignoring the type.

Rename `bitcode-in-rlib` option to `embed-bitcode`
This commit finishes work first pioneered in #70458 and started in #71528.
The `-C bitcode-in-rlib` option, which has not yet reached stable, is
renamed to `-C embed-bitcode` since that more accurately reflects what
it does now anyway. Various tests and such are updated along the way as
well.
This'll also need to be backported to the beta channel to ensure we
don't accidentally stabilize `-Cbitcode-in-rlib` as well.
