0b8a61b235 Auto merge of #118267 - compiler-errors:ambiguity-causes, r=spastorino
`AmbiguityCause` should not eagerly format strings

Minor tweak found when working on some coherence diagnostics stuff (towards `-Ztrait-solver=next-coherence` stabilization)

Rollup merge of #117871 - klensy:unused-pub, r=cjgillot
remove unused pub fns

This removes some unused `pub fn`; also fixes few obsoleted fn names or added fixmes with reminders to update them.

Rollup merge of #118000 - compiler-errors:placeholder-ty-outlives, r=aliemjay
Make regionck care about placeholders in outlives components

Currently, we don't consider a placeholder type `!T` to be a type component when it comes to processing type-outlives obligations. This means that they are essentially treated like unit values with no sub-components, and always outlive any region. This is problematic for `non_lifetime_binders`, and even more problematic for `with_negative_coherence`, since negative coherence uses placeholders as universals.

This PR adds `Component::Placeholder` which acts much like `Component::Param`. This currently causes a regression in some non-lifetime-binders tests because `for<T> T: 'static` doesn't imply itself when processing outlives obligations, so code like this will fail:

```
fn foo() where for<T> T: 'static {
  foo() //~ fails
}
```

Since the where clause doesn't imply itself. This requires making the `MatchAgainstHigherRankedOutlives` relation smarter when it comes to binders.

6b771f6b5a Auto merge of #117878 - gavinleroy:proper-depth-check, r=lcnr
Fix depth check in ProofTreeVisitor.

The hack to cutoff overflows and cycles in the new trait solver was incorrect. We want to inspect everything with depth [0..10].

This fix exposed a previously unseen bug, which caused the compiler to ICE when invoking `trait_ref` on a non-assoc type projection. I simply added the guard in the `AmbiguityCausesVisitor`, and updated the expected output for the `auto-trait-coherence` test which now includes the extra note:
```text
   |
   = note: upstream crates may add a new impl of trait `std::marker::Send` for type `OpaqueType` in future versions
```
