Rollup merge of #104595 - compiler-errors:poly-existential-predicate, r=lcnr 
Add `PolyExistentialPredicate` type alias

Wrapping `ExistentialPredicate`s in a binder is very common, and this alias already exists for the `PolyExistential{TraitRef,Projection}` types.

c5d82ed7a4 Auto merge of #102795 - lukas-code:constify-is-aligned-via-align-offset, r=oli-obk 
Constify `is_aligned` via `align_offset`

Alternative to https://github.com/rust-lang/rust/pull/102753

Make `align_offset` work in const eval (and not always return `usize::MAX`) and then use that to constify `is_aligned{_to}`.

Tracking Issue: https://github.com/rust-lang/rust/issues/104203

Rollup merge of #104593 - compiler-errors:rpitit-object-safety-spans, r=fee1-dead 
Improve spans for RPITIT object-safety errors

No reason why we can't point at the `impl Trait` that causes the object-safety violation.

Also [drive-by: Add is_async fn to hir::IsAsync](c4165f3a96), which touches clippy too.

Rollup merge of #104411 - lcnr:bivariance-nll, r=compiler-errors 
nll: correctly deal with bivariance

fixes #104409

when in a bivariant context, relating stuff should always trivially succeed. Also changes the mir validator to correctly deal with higher ranked regions.

Rollup merge of #104483 - oli-obk:santa-clauses-make-goals, r=compiler-errors 
Convert predicates into Predicate in the Obligation constructor

instead of having almost all callers do that.

This reduces a bit of boilerplate, and also paves the way for my work towards https://github.com/rust-lang/compiler-team/issues/531 (as it makes it easier to accept both goals and clauses where right now it only accepts predicates).

interpret: support for per-byte provenance

Also factors the provenance map into its own module.

The third commit does the same for the init mask. I can move it in a separate PR if you prefer.
