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 rust-lang#60068.
… clean up some run-make tests.
…, r=wesleywiser 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.

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 rust-lang#54054.
…lexcrichton Add codegen test for PGO instrumentation. This PR adds a codegen test that makes sure that LLVM actually generates instrumentation code when we enable PGO instrumentation in `rustc`. The second commit updates a test case to the new commandline option syntax introduced in rust-lang#59874.

Fix small errors in docs for `rchunks_exact` and `rchunks_exact_mut`.
