Tweak output for 'add line' suggestion

Special-case item attributes in the suggestion output

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list.
They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Alloc `hir::Lit` in an arena to remove the destructor from `Expr`

This allows allocating `Expr`s into a dropless arena, which is useful
for using length prefixed thing slices in HIR, since these can only be
allocated in the dropless arena and not in a typed arena. This is
something I'm working on.

Restrict `From<S>` for `{D,Subd}iagnosticMessage`.

Currently a `{D,Subd}iagnosticMessage` can be created from any type that
impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static,
str>`, which are reasonable. It also includes `&String`, which is pretty
weird, and results in many places making unnecessary allocations for
patterns like this:
```
self.fatal(&format!(...))
```
This creates a string with `format!`, takes a reference, passes the
reference to `fatal`, which does an `into()`, which clones the
reference, doing a second allocation. Two allocations for a single
string, bleh.

This commit changes the `From` impls so that you can only create a
`{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static,
str>`. This requires changing all the places that currently create one
from a `&String`. Most of these are of the `&format!(...)` form
described above; each one removes an unnecessary static `&`, plus an
allocation when executed. There are also a few places where the existing
use of `&String` was more reasonable; these now just use `clone()` at
the call site.

As well as making the code nicer and more efficient, this is a step
towards possibly using `Cow<'static, str>` in
`{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing
the `From<&'a str>` impls to `From<&'static str>`, which is doable, but
I'm not yet sure if it's worthwhile.

Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment:
```
// FIXME(davidtwco): can a `Cow<'static, str>` be used here?
```
This commit answers that question in the affirmative. It's not the most
compelling change ever, but it might be worth merging.

This requires changing the `impl<'a> From<&'a str>` impls to `impl
From<&'static str>`, which involves a bunch of knock-on changes that
require/result in call sites being a little more precise about exactly
what kind of string they use to create errors, and not just `&str`. This
will result in fewer unnecessary allocations, though this will not have
any notable perf effects given that these are error paths.

Note that I was lazy within Clippy, using `to_string` in a few places to
preserve the existing string imprecision. I could have used `impl
Into<{D,Subd}iagnosticMessage>` in various places as is done in the
compiler, but that would have required changes to *many* call sites
(mostly changing `&format("...")` to `format!("...")`) which didn't seem
worthwhile.

Put into one pass

Don't suppress manual_let_else if question_mark is allowed

If question_mark is allowed, there is no overlap any more,

Pass correct substs to `implements_trait` in `incorrect_impls`

`Copy<T>` does in fact not exist. The substs on the trait_ref contain

to `implements_trait`, which then nicely prepends the `Self` type
for us does not end will.

`unimplemented!` and `unreachable!`.

Signed-off-by: Panagiotis Foliadis <[email protected]>

Add "Known problems" section to `needless_borrow` documentation

[`tuple_array_conversions`]: move from `complexity` to `nursery`

Due to outstanding issues:
* rust-lang#11082
* rust-lang#11085
* rust-lang#11100 (rust-lang#11105)
* rust-lang#11124
* rust-lang#11144

[`arithmetic_side_effect`]: allow different rhs type

Add `imports_granularity = "Module"` to rustfmt.toml

Trigger a rebuild when CLIPPY_CONF_DIR changes

Set `unnecessary_cast` suggestion to `MaybeIncorrect` for pointer casts

Removing casts may cause type inference to stop working which requires
manual intervention

Bump Clippy version -> 0.1.73

Bump nightly version -> 2023-07-14

renamed lint
