Make fatal DiagnosticBuilder yield `!`
Fatal errors should really be fatal, so emitting them should cause us to exit at the same time.
Fine with just throwing away these changes if they're not worthwhile. Also, maybe we want to use an uninhabited enum instead of `!`.
r? `@eddyb` who has been working on `DiagnosticBuilder` stuff, feel free to reassign.
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.

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.

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.
