Also ignore clippy's "collapsible if..." lints.
(to de-duplicate my identities in the contributors list)
These reference names were very general, and used in other places.
Prefer projection candidates instead of param_env candidates for Sized predicates

Fixes rust-lang#89352

Also includes some drive by logging and verbose printing changes that I found useful when debugging this, but I can remove this if needed.

This is a little hacky - but imo no more than the rest of `candidate_should_be_dropped_in_favor_of`. Importantly, in a Chalk-like world, both candidates should be completely compatible.

Extend const_convert to rest of blanket core::convert impls

This adds constness to all the blanket impls in `core::convert` under the existing `const_convert` feature, tracked by rust-lang#88674.

Existing impls under that feature:

```rust
impl<T> const From<T> for T;
impl<T, U> const Into<U> for T where U: ~const From<T>;

impl<T> const ops::Try for Option<T>;
impl<T> const ops::FromResidual for Option<T>;

impl<T, E> const ops::Try for Result<T, E>;
impl<T, E, F> const ops::FromResidual<Result<convert::Infallible, E>> for Result<T, F> where F: ~const From<E>;
```

Additional impls:

```rust
impl<T: ?Sized, U: ?Sized> const AsRef<U> for &T where T: ~const AsRef<U>;
impl<T: ?Sized, U: ?Sized> const AsRef<U> for &mut T where T: ~const AsRef<U>;
impl<T: ?Sized, U: ?Sized> const AsMut<U> for &mut T where T: ~const AsMut<U>;

impl<T, U> const TryInto<U> for T where U: ~const TryFrom<T>;
impl<T, U> const TryFrom<U> for T where U: ~const Into<T>;
```

Add `#[track_caller]` to `mirbug`

When a "'no errors encountered even though `delay_span_bug` issued" error results from the `mirbug` function, the file location information points to the `mirbug` function itself, rather than its caller. This doesn't make sense, since the caller is the real source of the bug. Adding `#[track_caller]` will produce diagnostics that are more useful to anyone fixing the ICE.
Export `tcp::IntoIncoming`

Added in rust-lang#88339 but not publicly exported.
Use pre-interned symbols in a couple of places

Re-open of rust-lang#92733 as bors glitched.

Clean up some links in RELEASES

Make `opt_const_param_of` work in the presence of `GenericArg::Infer`

highly recommend viewing the first and second commits on their own rather than looking at file changes 🤣

Because we filtered args down to just const args we would ignore `GenericArg::Infer` which made us get a `arg_index` which was wrong by however many const `GenericArg::Infer` came previously

[example](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=46dba6a53aca6333028a10908ef16e0b) of the [bugs](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=a8eebced26eefa4119fc2e7ae0c76de6) fixed.
