Deprecate the core::raw / std::raw module
It only contains the `TraitObject` struct which exposes components of wide pointer. Pointer metadata APIs are designed to replace this: https://github.com/rust-lang/rust/issues/81513
The --bulk-dirs argument was removed for rust-docs in commit
c768ce1384 and rustc-docs in commit
8ca46fc7a8 (#79788), presumably by
mistake; that slowed down installation of rust-docs from under a
second to some twenty *minutes*. Restoring --bulk-dirs reverses this
slowdown.
Fixes#80684.

Add some #[inline(always)] to arithmetic methods of integers
I tried to add it only to methods which return results of intrinsics and don't have any branching.
Branching could made performance of debug builds (`-Copt-level=0`) worse.
Main goal of changes is allowing wider optimizations in `-Copt-level=1`.

`@rustbot` modify labels: rollup
`fast-math` implies things like functions not being able to accept as an
argument or return as a result, say, `inf` which made these functions
confusingly named or behaving incorrectly, depending on how you
interpret it. Since the time when these intrinsics have been implemented
the intrinsics user's (stdsimd) approach has changed significantly and
so now it is required that these intrinsics operate normally rather than
in "whatever" way.
Fixes#84268
Add documentation to help people find `Ipv4Addr::UNSPECIFIED`
People looking for `INADDR_ANY` don't always find `Ipv4Addr::UNSPECIFIED`;
add some documentation to help.
rustdoc: move some search code into search.js
This reduces main.s from 3094 lines to 1587. Also it saves some bytes
of download in the case where search isn't used.
There were a fair number of variables that needed to be accessible in
both main.js and search.js, but I didn't want to put too many symbols in
the global namespace, so I consolidated much of the search-related
state and functions into a new object `window.searchState`.

rustdoc: use more precise relative URLs
This is a fairly large diff, and will probably conflict with https://github.com/rust-lang/rust/pull/82815 since it reduces (but does not eliminate) the use of the old depth variable.
Instead of using a depth counter and adding "../" to get to the top, this commit makes rustdoc actually compare the path of what it's linking from to the path that it's linking to. This makes the resulting HTML shorter.
Here's a comparison of one of the largest (non-source) files in the Rust standard library docs (about 4% improvement before gzipping).
$ wc -c struct.Wrapping.old.html struct.Wrapping.new.html
2387389 struct.Wrapping.old.html
2298538 struct.Wrapping.new.html
Most if it can be efficiently gzipped away.
$ wc -c struct.Wrapping.old.html.gz struct.Wrapping.new.html.gz
70679 struct.Wrapping.old.html.gz
70050 struct.Wrapping.new.html.gz
But it also makes a difference in the final DOM size, reducing it from 91MiB to 82MiB.
No compiler changes as part of this -- just new unstable traits and impls thereof.
The goal here is to add the things that aren't going to break anything, to keep the feature implementation simpler in the next PR.

Error when compiletest is passed duplicate revisions
Currently, we allow the user to write things like
'// revisions: rpass1 rpass1', which will not test what they were
intending to test.
rustdoc: get rid of unused path printing code
The code for printing a raw path is only used in utils.rs, which only prints the alternative (non-HTML) format. Path has
a function that does the same thing without HTML support, so use that instead.

Builtin derive macros: fix error with const generics default
This fixes a bug where builtin derive macros (like Clone, Debug) would basically copy-paste the default from a const generic, causing a compile error with very confusing message - it would say defaults are not allowed in impl blocks, while pointing at struct/enum/union definition.
Detect when suggested paths enter extern crates more rigorously
When reporting resolution errors, the compiler tries to avoid suggesting importing inaccessible paths from other crates. However, the search for suggestions only recognized when it was entering a crate root directly, and so failed to recognize a path like `crate::module::private_item`, where `module` was imported from another crate with `use other_crate::module`, as entering another crate.

rustdoc: clean up and test macro visibility print
This fixes the overly-complex invariant mentioned in <https://github.com/rust-lang/rust/pull/83237#issuecomment-815346570>, where the macro source can't have any links in it only because the cache hasn't been populated yet.
