Bump libc dependency of std to 0.2.88.
This PR bumps the `libc` dependency of `std` to 0.2.88. This will fix `TcpListener::accept` for Android on x86 platforms (31a2777d8f).
This will really finally fix https://github.com/rust-lang/rust/issues/82400 for the main branch :)

Update minifier dependency version
Very small PR simply upgrading the minifier-rs version we use in rustdoc.
Some details might be useful: there were a few bug fixes and a lot of cleanup/code improvements.

Update tracing to 0.1.25
* Update tracing from 0.1.18 to 0.1.25
* Update tracing-subscriber from 0.2.13 to 0.2.16
* Update tracing-tree from 0.1.6 to 0.1.8
* Add pin-project-lite to the list of allowed dependencies (it is now a direct dependency of tracing).
Always compile rustdoc with debug logging enabled when `download-rustc` is set
Previously, logging at DEBUG or below would always be silenced, because
rustc compiles tracing with the `static_max_level_info` feature. That
makes sense for release artifacts, but not for developing rustdoc.
Instead, this compiles two different versions of tracing: one in the
release artifacts, distributed in the sysroot, and a new version
compiled by rustdoc. Since `rustc_driver` is always linked to the
version of sysroot, this copy/pastes `init_env_logging` into rustdoc.
To avoid compiling an unnecessary version of tracing when
`download-rustc` isn't set, this adds a new `using-ci-artifacts`
feature for rustdoc and passes that feature in bootstrap.
Addresses https://github.com/rust-lang/rust/issues/81930. This builds on https://github.com/rust-lang/rust/pull/79540.

Update measureme dependency to the latest version
This version adds the ability to use `rdpmc` hardware-based performance
counters instead of wall-clock time for measuring duration. This also
introduces a dependency on the `perf-event-open-sys` crate on Linux
which is used when using hardware counters.

Replace const_cstr with cstr crate
This PR replaces the `const_cstr` macro inside `rustc_data_structures` with `cstr` macro from [cstr](https://crates.io/crates/cstr) crate.
The two macros basically serve the same purpose, which is to generate `&'static CStr` from a string literal. `cstr` is better because it validates the literal at compile time, while the existing `const_cstr` does it at runtime when `debug_assertions` is enabled. In addition, the value `cstr` generates can be used in constant context (which is seemingly not needed anywhere currently, though).

Make the `Query` enum a simple struct.
A lot of code in `rustc_query_system` is generic over it, only to encode an exceptional error case: query cycles.
The delayed computations are now done at cycle detection.
rustc_codegen_ssa: tune codegen according to available concurrency
This change tunes ahead-of-time codegening according to the amount of
concurrency available, rather than according to the number of CPUs on
the system. This can lower memory usage by reducing the number of
compiled LLVM modules in memory at once, particularly across several
rustc instances.
Previously, each rustc instance would assume that it should codegen
ahead of time to meet the demand of number-of-CPUs workers. But often, a
rustc instance doesn't have nearly that much concurrency available to
it, because the concurrency availability is split, via the jobserver,
across all active rustc instances spawned by the driving cargo process,
and is further limited by the `-j` flag argument. Therefore, each rustc
might have had several times the number of LLVM modules in memory than
it really needed to meet demand. If the modules were large, the effect
on memory usage would be noticeable.
With this change, the required amount of ahead-of-time codegen scales up
with the actual number of workers running within a rustc instance. Note
that the number of workers running can be less than the actual
concurrency available to a rustc instance. However, if more concurrency
is actually available, workers are spun up quickly as job tokens are
acquired, and the ahead-of-time codegen scales up quickly as well.

Borrowck: refactor visited map to a bitset
This PR refactors `Borrows` and the `precompute_borrows_out_of_scope` function so that this initial phase has a much reduced memory pressure. This is achieved by reducing what is stored on the heap, and also reusing heap memory as much as possible.
This allows a build system to indicate a location in its own dependency
specification files (eg Cargo's `Cargo.toml`) which can be reported
along side any unused crate dependency.
This supports several types of location:
- 'json' - provide some json-structured data, which is included in the json diagnostics
in a `tool_metadata` field
- 'raw' - emit the provided string into the output. This also appears as a json string in
`tool_metadata`.
If no `--extern-location` is explicitly provided then a default json entry of the form
`"tool_metadata":{"name":<cratename>,"path":<cratepath>}` is emitted.
For better throughput during parallel processing by LLVM, we used to sort
CGUs largest to smallest. This would lead to better thread utilization
by, for example, preventing a large CGU from being processed last and
having only one LLVM thread working while the rest remained idle.
However, this strategy would lead to high memory usage, as it meant the
LLVM-IR for all of the largest CGUs would be resident in memory at once.
Instead, we can compromise by ordering CGUs such that the largest and
smallest are first, second largest and smallest are next, etc. If there
are large size variations, this can reduce memory usage significantly.
Add AArch64 big-endian and ILP32 targets
This PR adds 3 new AArch64 targets:
- `aarch64_be-unknown-linux-gnu`
- `aarch64-unknown-linux-gnu_ilp32`
- `aarch64_be-unknown-linux-gnu_ilp32`
It also fixes some ABI issues on big-endian ARM and AArch64.
Upgrade Chalk
~~Blocked on rust-lang/chalk#670~~
~~Now blocked on rust-lang/chalk#680 and release~~
In addition to the straight upgrade, I also tried to fix some tests by properly returning variables and max universes in the solution. Unfortunately, this actually triggers the same perf problem that rustc traits code runs into in `canonicalizer`. Not sure what the root cause of this problem is, or why it's supposed to be solved in chalk.

Add error message for private fn
Attempts to add a more detailed error when a `const_evaluatable` fn from another scope is used inside of a scope which cannot access it.
r? ````@lcnr````
* Reuse memory
* simplify `next_def_id`, avoid multiple hashing and unnecessary lookups
* remove `all_fake_def_ids`, use the global map instead (probably not a good step toward parallelization, though...)
* convert `add_deref_target` to iterative implementation
* use `ArrayVec` where we know the max number of elements
* minor touchups here and there
* avoid building temporary vectors that get appended to other vectors
At most places I may or may not be doing the compiler's job is this PR.
Split rustdoc JSON types into separately versioned crate
For now just an in-tree change.
In the future, this may be exposed as a standalone crate with standard semver.
