Inline methods of Path and OsString
These methods are not generic, and therefore aren't candidates for cross-crate inlining without an `#[inline]` attribute.
Fix <unknown> queries and add more timing info to render_html
Closes https://github.com/rust-lang/rust/issues/81251.
## Fix `<unknown>` queries
This happened because `alloc_query_strings` was never called.
## Add more timing info to render_html
This still has some issues I'm not sure how to work out:
- `create_renderer` and `renderer_after_krate` aren't shown by default.
I want something like `verbose_generic_activity_with_arg`, but it doesn't exist.
I'm also not sure how to show activities that aren't on by default - I
tried `-Z self-profile -Z self-profile-args=all`, but it didn't show up.

- Fix some issues with `cargo doc` and the new feature resolver. (rust-lang/cargo#9077)
- Implement support for rust-version field in project metadata (rust-lang/cargo#8037)
- Fix a bug in Cargo's cyclic dep graph detection (rust-lang/cargo#9075)
- Typo correction: artifcats -> artifacts (rust-lang/cargo#9081)
- Remove stray backtick from doc (rust-lang/cargo#9079)
More clear documentation for NonNull<T>
Rephrase and hopefully clarify the discussion of covariance in `NonNull<T>` documentation.
I'm very much not an expert so someone should definitely double check the correctness of what I'm saying. At the same time, the new language makes more sense to me, so hopefully it also is more logical to others whose knowledge of covariance basically begins and ends with the [Rustonomicon chapter](https://doc.rust-lang.org/nomicon/subtyping.html).
Related to #48929.
- Add the module name to `pre_AST_expansion_passes` and don't make it a
verbose event (since it normally doesn't take very long, and it's
emitted many times)
- Don't make the following rustdoc events verbose; they're emitted many times.
+ build_extern_trait_impl
+ build_local_trait_impl
+ build_primitive_trait_impl
+ get_auto_trait_impls
+ get_blanket_trait_impls
- Remove `get_auto_trait_and_blanket_synthetic_impls`; it's wholly
covered by get_{auto,blanket}_trait_impls and not very useful.
This avoids each tool having to separately find and call
`self_profile_alloc_strings`.
- Don't compute the global context if it hasn't yet been computed
This avoids giving extraneous errors about unresolved names if an error
occurs during parsing.
This is a temporary change only, as we wait to resolve dynamic dispatch issues. The `Stream::next` method and corresponding documentation are expected to be fully restored once we have a path to proceed.

avoid promoting division, modulo and indexing operations that could fail
For division, `x / y` will still be promoted if `y` is a non-zero integer literal; however, `1/(1+1)` will not be promoted any more.
While at it, also see if we can reject promoting floating-point arithmetic (which are [complicated](https://github.com/rust-lang/unsafe-code-guidelines/issues/237) so maybe we should not promote them).
This will need a crater run to see if there's code out there that relies on these things being promoted.
If we can land this, promoteds in `fn`/`const fn` cannot fail to evaluate any more, which should let us do some simplifications in codegen/Miri!
