Fix misuse of rev attribute on <a> tag
The `rev` attribute is supposed to talk about "ownership" as far as I could found out. This attribute seems not very well defined in the HTML spec and its usage in rustdoc is suboptimal.
It was found out in https://github.com/rust-lang/rust/pull/87149.

Add -Zfuture-incompat-test to assist with testing future-incompat reports.
This adds a `-Zfuture-incompat-test` cli flag to assist with testing future-incompatible reports. This flag causes all lints to be treated as a future-incompatible lint, and will emit a report for them. This is being added so that Cargo's testsuite can reliably test the reporting infrastructure. Right now, Cargo relies on using array_into_iter as a test subject. Since the breaking "future incompatible" lints are never intended to last forever, this means Cargo's testsuite would always need to keep changing to choose different lints (for example, #86330 proposed dropping that moniker for array_into_iter). With this flag, Cargo's tests can trigger any lint and check for the report.

Reuse CrateNum for proc-macro crates even when cross-compiling
Proc-macros are always compiled for the host, so this should be the same
in every way as recompiling the crate.
I am not sure why the previous code special-cased the target, since the
compiler properly gives an error when trying to load a crate for a
different host:
```
error[E0461]: couldn't find crate `dependency` with expected target triple x86_64-unknown-linux-gnu
--> /home/joshua/rustc4/src/test/ui/cfg-dependent.rs:8:2
|
LL | dependency::is_64();
| ^^^^^^^^^^
|
= note: the following crate versions were found:
crate `dependency`, target triple i686-unknown-linux-gnu: /home/joshua/rustc4/build/x86_64-unknown-linux-gnu/test/ui/cfg-dependent/auxiliary/libdependency.so
```
I think another possible fix is to remove the check altogether. But I'm
not sure, and this fix works, so I'm not making the larger change here.
Fixes https://github.com/rust-lang/rust/issues/56935.

rustdoc: Remove unnecessary `extern crate` aliases

Fix codeblocks overflow
Fixes #87043.
Instead of completely relying on `pulldown-cmark` (and its potential changes), I decided to move the generation of codeblocks HTML directly in rustdoc so we can unify the DOM and the CSS classes.

expand: Support helper attributes for built-in derive macros
This is needed for https://github.com/rust-lang/rust/pull/86735 (derive macro `Default` should have a helper attribute `default`).
With this PR we can specify helper attributes for built-in derives using syntax `#[rustc_builtin_macro(MacroName, attributes(attr1, attr2, ...))]` which mirrors equivalent syntax for proc macros `#[proc_macro_derive(MacroName, attributes(attr1, attr2, ...))]`.
Otherwise expansion infra was already ready for this.
The attribute parsing code is shared between proc macro derives and built-in macros (`fn parse_macro_name_and_helper_attrs`).

Handle non-integer const generic parameters in debuginfo type names.
This PR fixes an ICE introduced by https://github.com/rust-lang/rust/pull/85269 which started emitting const generic arguments for debuginfo names but did not cover the case where such an argument could not be evaluated to a flat string of bits.
The fix implemented in this PR is very basic: If `try_eval_bits()` fails for the constant in question, we fall back to generating a stable hash of the constant and emit that instead. This way we get a (virtually) unique name and side step the problem of generating a string representation of a potentially complex value.
The downside is that the generated name will be rather opaque. E.g. the regression test adds a function `const_generic_fn_non_int<()>` which is then rendered as `const_generic_fn_non_int<{CONST#fe3cfa0214ac55c7}>`. I think it's an open question how to deal with this more gracefully.
I'd be interested in ideas on how to do this better.

This is leftover from when `doctest` used to be called `test`. Remove it
now, it's unnecessary and makes the code harder to read.
