This is no longer necessary with the new pass manager.

-C passes=list was printing passes for the legacy pass manager.
Use PassBuilder::printPassNames() to print NewPM passes instead.

Deny capturing late-bound non-lifetime param in anon const

Introduce a new AnonConstBoundary so we can detect when we capture a late-bound non-lifetime param with `non_lifetime_binders` enabled.

In the future, we could technically do something like introduce an early-bound parameter on the anon const, and stick the late-bound param in its substs (kinda like how we turn late-bound lifetimes in opaques into early-bound ones). But for now, just deny it so we don't ICE.

Fixes rust-lang#108191

Remove legacy PM leftovers

This drops two leftovers of legacy PM usage:
 * We don't need to initialize passes anymore.
 * The pass listing was still using legacy PM passes. Replace it with the corresponding new PM listing.

Fix another ICE in `point_at_expr_source_of_inferred_type`

Types coming from method probes must only be investigated *structurally*, since they often contain escaping infer variables from generalization and autoderef. We already have a hack in this PR that erases variables from types, so just use that.

Fixes rust-lang#108664

The note attached to this error is pretty bad:

```
here the type of `primes` is inferred to be `[_]`
```

But that's unrelated to the PR.

Side-note: This is a pretty easy to trigger beta regression, so I've nominated it. Alternatively, I'm slightly inclined to remove this code altogether until it can be reformulated to be more accurate and less ICEy.
