Remove the remains of query categories
Back in October 2020 in #77830 ``@cjgillot`` removed the query categories information from the profiler, but the actual definitions which query was in which category remained, although unused.
Here I clean that up, to simplify the query definitions even further.
It's unfortunate that this loses all the context for `git blame`, ~~but I'm working on moving those query definitions into `rustc_query_system`, which will lose that context anyway.~~ EDIT: Might not work out.
The functional changes are in the first commit. The second one only changes the indentation.
Improve handling of spans around macro result parse errors
Fixes#81543
After we expand a macro, we try to parse the resulting tokens as a AST
node. This commit makes several improvements to how we handle spans when
an error occurs:
* Only ovewrite the original `Span` if it's a dummy span. This preserves
a more-specific span if one is available.
* Use `self.prev_token` instead of `self.token` when emitting an error
message after encountering EOF, since an EOF token always has a dummy
span
* Make `SourceMap::next_point` leave dummy spans unused. A dummy span
does not have a logical 'next point', since it's a zero-length span.
Re-using the span span preserves its 'dummy-ness' for other checks
rustdoc: Note why `rustdoc::html::markdown` is public
Almost all of the modules are crate-private, except for
`rustdoc::json::types`, which I believe is intended to be for public
use; and `rustdoc::html::markdown`, which is used externally by the
error-index generator and so has to be public.

Add some tests for associated-type-bounds issues
Closes#38917Closes#40093Closes#43475Closes#63591#47897 is likely closable too, but it needs an MCVE
~~#38917, #40093, #43475, #47897 all are mislabeled and shouldn't have the `F-associated-type-bounds` label~~
~~#71685 is also mislabeled as commented on in that thread~~
Add lint for 2229 migrations
Implements the first for RFC 2229 where we make the decision to migrate a root variable based on if the type of the variable needs Drop and if the root variable would be moved into the closure when the feature isn't enabled.

Update armhf-gnu to Ubuntu 20.04
This requires updating the used Linux kernel to avoid an assembler
error, the used busybox version to avoid a linker error, the used
rootfs to match the host version and the qemu flags to work with
the newer version.

- This allows us add fake information after handling migrations if
needed.
- Capture analysis also priortizes what we see earlier, which means
fake information should go in last.

Sync rustc_codegen_cranelift
The highlight of this sync are abi compatibility with cg_llvm allowing mixing of cg_clif and cg_llvm compiled crates and switching to the x64 cranelift backend based on the new backend framework.

Fix calling convention for CRT startup
My PR #81478 used the wrong calling convention for a set of
functions that are called by the CRT. These functions need to use
`extern "C"`.
This would only affect x86, which is the only target (that I know of)
that has multiple calling conventions.

Avoid building LLVM just for llvm-dwp
When the LLVM backend is disabled, the llvm-project submodule is not checked out by default. This breaks the bootstrap test for cg_clif. As cg_clif doesn't support split debuginfo anyway llvm-dwp is not necessary. Other backends would likely not want to build LLVM just for llvm-dwp either.
Fixes https://github.com/bjorn3/rustc_codegen_cranelift/issues/1119
Indicate both start and end of pass RSS in time-passes output
Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.
Also, improve alignment of columns.
Sample of output:
```
time: 0.739; rss: 607MB -> 637MB item_types_checking
time: 8.429; rss: 637MB -> 775MB item_bodies_checking
time: 11.063; rss: 470MB -> 775MB type_check_crate
time: 0.232; rss: 775MB -> 777MB match_checking
time: 0.139; rss: 777MB -> 779MB liveness_and_intrinsic_checking
time: 0.372; rss: 775MB -> 779MB misc_checking_2
time: 8.188; rss: 779MB -> 1019MB MIR_borrow_checking

Let io::copy reuse BufWriter buffers
This optimization will allow users to implicitly set the buffer size for io::copy by wrapping the writer into a `BufWriter` if the default block size is insufficient, which should fix#49921
Due to min_specialization limitations this approach only works with `BufWriter` but not for `BufReader<R>` since `R` is unconstrained and thus the necessary specialization on `R: Read` is not always applicable. Once specialization becomes more powerful this optimization could be extended to look at the reader and writer side and use whichever buffer is larger.
Implement Rust 2021 panic
This implements the Rust 2021 versions of `panic!()`. See https://github.com/rust-lang/rust/issues/80162 and https://github.com/rust-lang/rfcs/pull/3007.
It does so by replacing `{std, core}::panic!()` by a bulitin macro that expands to either `$crate::panic::panic_2015!(..)` or `$crate::panic::panic_2021!(..)` depending on the edition of the caller.
This does not yet make std's panic an alias for core's panic on Rust 2021 as the RFC proposes. That will be a separate change: c5273bdfb2 That change is blocked on figuring out what to do with https://github.com/rust-lang/rust/issues/80846 first.
Almost all of the modules are crate-private, except for
`rustdoc::json::types`, which I believe is intended to be for public
use; and `rustdoc::html::markdown`, which is used externally by the
error-index generator and so has to be public.
