Reword `trivial_casts` lint in rustc book to better explain what it does.
The current description of the trivial casts lint under the "allowed
by default" listing in the rustc book indicates the lint is for casts
which may be removed, which is less clear than saying it's for casts
which may be replaced by coercion (which is the wording used by the
error message included in the doc).
This commit changes the wording slightly to better describe what the
lint does.
This issue bit me in some recent code where I was attempting to
convert a `Vec<SomeType>` to a `Vec<SomeTraitObject>`, and
hit my project-wide `#![deny(trivial_casts)]` with
`map(|o| Box::new(o) as TraitObject)`. I'd read the book docs for
`trivial_casts` and was surprised by the error, as I took it to mean
the cast ought to be removed (rather than replaced by ascription
in this case). Removing the cast meant other code didn't compile,
and I then found issues like #23742 and realized my misunderstanding.

[AVR] Replace broken 'avr-unknown-unknown' target with 'avr-unknown-gnu-atmega328' target
The `avr-unknown-unknown` target has never worked correctly, always trying to invoke
the host linker and failing. It aimed to be a mirror of AVR-GCC's
default handling of the `avr-unknown-unknown' triple (assume bare
minimum chip features, silently skip linking runtime libraries, etc).
This behaviour is broken-by-default as it will cause a miscompiled executable
when flashed.
This patch improves the AVR builtin target specifications to instead
expose only a 'avr-unknown-gnu-atmega328' target. This target system is
`gnu`, as it uses the AVR-GCC frontend along with avr-binutils. The
target triple ABI is 'atmega328'.
In the future, it should be possible to replace the dependency on
AVR-GCC and binutils by using the in-progress AVR LLD and compiler-rt support.
Perhaps at that point it would make sense to add an
'avr-unknown-unknown-atmega328' target as a better default when
implemented.
There is no current intention to add in-tree AVR target specifications for other
AVR microcontrollers - this one can serve as a reference implementation
for other devices via `rustc --print target-spec-json
avr-unknown-gnu-atmega328p`.
There should be no users of the existing 'avr-unknown-unknown' Rust
target as a custom target specification JSON has always been
recommended, and the avr-unknown-unknown target could never pass the
linking step anyway.

Move platform support to the rustc book.
This moves the [Platform Support](https://forge.rust-lang.org/release/platform-support.html) page from the forge to the rustc book. There are several reasons for doing this:
* The forge is not really oriented towards end-users (it mostly contains infrastructure, governance and policy, internal team pages, etc.). This platform support page is useful to user to know which targets are supported.
* This page can now be updated in-sync with any PRs that add or remove a target, or change its status.
* This is now automatically checked on CI to verify the list does not get out of sync. Currently it only checks the presence/absence of an entry, but more sophisticated checks could be added in the future.
I'm not 100% certain this is the best location, but I think it fits. I'd like to see the rustc guide continue to grow, including things like linking information and more platform-specific details.

A few updates:
- Some minor wording and formatting changes.
- Remove the `cargo` column.
- Explain the columns up-front.
- Add no-wrap on the target-triple, which looks better to me.
- Minor mention on how to install support for a built-in target via rustup.
|
|
|
|
- Update the list of supported architectures.
- Clarify issues with LLVM's use of reserved registers.
