Fixes 5088
Previously, rustfmt would add a new comment line anytime it reformatted
an itemized block within a comment when ``wrap_comments=true``. This
would lead to rustfmt adding empty comments with trailing whitespace.
Now, new comment lines are only added if the original comment spanned
multiple lines, if the comment needs to be wrapped, or if the comment
originally started with an empty comment line.
Adds the ``nightly_only_test`` and ``stable_only_test`` attribute macros
that prevent or allow certain tests to compile on nightly and stable
respectively. This is achieved through conditionally outputting the
tests TokenStream.
If CFG_RELEASE_CHANNEL is not set, it's assumed that we're running in a
nightly environment.
To mark a test as nightly only:
#[nightly_only_test]
#[test]
fn only_run_on_nightly() {
...
}
To mark a test a stable only:
#[stable_only_test]
#[test]
fn only_run_on_stable() {
...
}
* Add a few missing tracking issues in Configurations.md

All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.

This behavior was noticed when using the ``trailing_comma = "Never"``
configuration option (5012).
This behavior was also noticed when using default configurations (4850).
rustfmt would add a trailing space to where clause bounds that had an
empty right hand side.
Now no trailing space is added to the end of these where clause bounds.

Trailing comments at the end of the root Module were removed because the
module span did not extend until the end of the file.
The root Module's span now encompasses the entire file, which ensures
that no comments are lost when using ``#![rustfmt::skip]``
Resolves 5038
rust-lang/rust builds now document rustfmt (rust-lang/rust#87119). The
build process is updated with doc checks to ensure that rustfmt doesn't
introduce warnings.
Warnings are treated as hard errors in rust-lang/rust and won't show
until bors tests the changes (refs rust-lang/rust#90087).
