Skip needless bitset for debuginfo
Found this while digging around looking at the inlining logic.
Seemed obvious enough so I decided to try to take care of it.
Is this what you had in mind, `@eddyb?`

Allow comparing `Vec`s with different allocators using `==`
See https://stackoverflow.com/q/71021633/7884305.
I did not changed the `PartialOrd` impl too because it was not generic already (didn't support `Vec<T> <=> Vec<U> where T: PartialOrd<U>`).
Does it needs tests?
I don't think this will hurt type inference much because the default allocator is usually not inferred (`new()` specifies it directly, and even with other allocators, you pass the allocator to `new_in()` so the compiler usually knows the type).
I think this requires FCP since the impls are already stable.
Clarify that ManuallyDrop<T> has same layout as T
This PR implements the documentation change under discussion in https://github.com/rust-lang/unsafe-code-guidelines/issues/302. It should not be approved or merged until the discussion there is resolved.
It's only needed for macro expansion, not as a general element in the
AST. This commit removes it, adds `NtOrTt` for the parser and macro
expansion cases, and renames the variants in `NamedMatch` to better
match the new type.
Fix typo in `String::try_reserve_exact` docs
Copying the pattern from `Vec::try_reserve_exact` and `String::try_reserve`,
it looks like this doc comment is intending to refer to the currently-being-documented
function.
Provide suggestion for missing `>` in a type parameter list
When encountering an inproperly terminated type parameter list, provide
a suggestion to close it after the last non-constraint type parameter
that was successfully parsed.
Fix#94058.
This was so verbose before that it made it hard to see what effect the flag actually had.

Bump the ripgrep commit exercised by cargotest
This update goes from 3de31f7527 (Aug 1, 2019) to current master, ced5b92aa9 (March 21, 2022).
I need this in order to pick up https://github.com/BurntSushi/ripgrep/pull/1722, which picked up https://github.com/BurntSushi/bstr/pull/58, which unblocks https://github.com/rust-lang/rust/pull/95345. Ripgrep uses the Debug representation of a `BStr` in some of its tests. In old versions of bstr, that used to just use the standard library's `escape_debug()` implementation, so the output ends up being sensitive to whether the standard library renders character 0 as `\u{0}` or as `\0`. The newer bstr always renders character 0 as `\0` and ripgrep's test suite has been correspondingly updated.

ARMv6K Horizon OS has_thread_local support
cc. ```@ian-h-chamberlain```
cc. ```@AzureMarker```
Being an ARM target, it has always had built-in support for `#[thread_local]`. This PR comes in just now because we were testing `std::thread` support with `thread_local_dtor`s. This will hopefully be the last PR for the target specification, unless anymore features will be needed as time goes on.

Skip pointing out ambiguous impls in alloc/std crates too in inference errors
This generalizes the logic in `annotate_source_of_ambiguity` to skip printing ambiguity errors traits in `alloc` and `std` as well, not just `core`.
While this does spot-fix the issue mentioned below, it would be nicer to generalize this logic, for example to detect when the trait predicate's `self_ty` has any numerical inference variables. Is it worthwhile to scrap this solution for one like that?
