Fix small errors in docs for `rchunks_exact` and `rchunks_exact_mut`.
The documentation for `rchunks_exact` said it started at the beginning
of the slice, bit it actually starts at the end of the slice.
In addition, there were a couple of "of the slice of the slice"
duplicate phrases going on for `rchunks_exact` and `rchunks_exact_mut`.
This fixes#60068.
Suggest appropriate path when calling associated item on bare types
When looking at the documentation for `std::f32` or `std::str`, for
example, it is easy to get confused and assume `std::f32` and `f32`
are the same thing. Because of this, it is not uncommon to attempt
writing `f32::consts::PI` instead of the correct
`std::f32::consts::PI`. When encountering the former, which results
in an access error due to it being an inexistent path, try to access
the same path under `std`. If this succeeds, this information is
stored for later tweaking of the final E0599 to provide an
appropriate suggestion.
Fix#26760, fix#46660.
implement specialized nth_back() for Bytes, Fuse and Enumerate
Hi,
After my first PR has been successfully merged, here is my second pull request :-)
Also this PR contains some specializations for the problem discussed in #54054.
Implement event filtering for self-profiler.
This is a first sketch for event filtering in the self-profiler, something that we'll want in order to keep profiling overhead low in the common case. The PR contains the commits from https://github.com/rust-lang/rust/pull/59515 and, for the moment, is meant for performance testing.

This suggestion applies to both E0233 and E0599 and is only checked
when the first ident of a path corresponds to a primitive type.

I'd like to fix this but I don't know what to do.
I will work on later. Please let me know if you have any solutions.

Resolve inconsistency in error messages between "parameter" and "variable".
The inconsistency was introduced in 104fe1c4db (#33619), when a label saying `type variable` was added to an error with a message talking about `type parameters`.
Given that `parameter` is far more prevalent when referring to generics in the context of Rust, IMO it should be that in both the message and the label.
