Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!
Remove not(stage0) from deny(warnings)
Historically this was done to accommodate bugs in lints, but there hasn't been a
bug in a lint since this feature was added which the warnings affected. Let's
completely purge warnings from all our stages by denying warnings in all stages.
This will also assist in tracking down `stage0` code to be removed whenever
we're updating the bootstrap compiler.

Resetting the terminal should first try `sgr0` (as per the comment), not
`sg0` which I believe to be a typo.
This will at least fix rustc output in Emacs terminals (e.g., ansi-term)
with `TERM=eterm-color` which does not provide the next fallback `sgr`. In
such a terminal, the final fallback `op` (`\e[39;49`) is used which
resets only colors, not all attributes. This causes all text to be
printed in bold from the first string printed in bold by rustc onwards,
including the terminal prompt and the output from all following commands.
The typo seems to have been introduced by #29999
Automated conversion using the untry tool [1] and the following command:
```
$ find -name '*.rs' -type f | xargs untry
```

The standard library doesn't depend on rustc_bitflags, so move it to explicit
dependencies on all other crates. Additionally, the arena/fmt_macros deps could
be dropped from libsyntax.
This commit removes the `-D warnings` flag being passed through the makefiles to
all crates to instead be a crate attribute. We want these attributes always
applied for all our standard builds, and this is more amenable to Cargo-based
builds as well.
Note that all `deny(warnings)` attributes are gated with a `cfg(stage0)`
attribute currently to match the same semantics we have today
This brings across changes made to the term library to libterm. This
includes removing instances or unwrap, fixing format string handling, and
removing a TODO.
This fix does not bring all changes across, as term now relies on cargo
deps that cannot be brought into the rust build at this stage, but has
attempted as best to cross port changes not relying on this. This notably
limits extra functionality since implemented int he Terminal trait in
Term.
This is in partly in response to rust issue #29992.
