9bb6fbe261 Auto merge of #113376 - Nilstrieb:pointer-coercions-are-not-casts-because-that-sounds-way-to-general-aaaa, r=oli-obk
Rename `adjustment::PointerCast` and variants using it to `PointerCoercion`

It makes it sounds like the `ExprKind` and `Rvalue` are supposed to represent all pointer related casts, when in reality their just used to share a little enum variants. Make it clear there these are only coercions and that people who see this and think "why are so many pointer related casts not in these variants" aren't insane.

This enum was added in #59987. I'm not sure whether the variant sharing is actually worth it, but this at least makes it less confusing.

sanity check field offsets in unsizeable structs

As promised in https://github.com/rust-lang/rust/pull/112062#issuecomment-1567494994, this PR extends the layout sanity checks to ensure that structs fields don't move around when unsizing and prevent issues like https://github.com/rust-lang/rust/issues/112048 in the future. Like most other layout sanity checks, this only runs on compilers with debug assertions enabled.

Here is how it looks when it fails:
```text
error: internal compiler error: compiler/rustc_ty_utils/src/layout.rs:533:21: unsizing GcNode<std::boxed::Box<i32>> changed field order!

bd8aabef31 Auto merge of #113291 - oli-obk:pretty_print_mir_const, r=RalfJung
Specialize `try_destructure_mir_constant` for its sole user (pretty printing)

We can't remove the query, as we need to invoke it from rustc_middle, but can only implement it in mir interpretation/const eval.

r? `@RalfJung` for a first round.

While we could move all the logic into pretty printing, that would end up duplicating a bit of code with const eval, which doesn't seem great either.

Rollup merge of #113321 - BoxyUwU:move_constkind_to_typeir, r=oli-obk
Move `ty::ConstKind` to `rustc_type_ir`

Needed this in another PR for custom debug impls, and this will also be required to move the new solver into a separate crate that does not use `TyCtxt` so that r-a and friends can depend on the trait solver.

Rebased on top of #113325, only the second and third commits needs reviewing

Rollup merge of #113320 - oli-obk:eval_obligation_query, r=petrochenkov,BoxyUwU
Add some extra information to opaque type cycle errors

Plus a bunch of cleanups.

This should help users debug query cycles due to auto trait checking. We'll probably want to fix cycle errors in most (or all?) cases by looking at the current item's hidden types (new solver does this), and by delaying the auto trait checks to after typeck.

Make simd_shuffle_indices use valtrees

This removes the second-to-last user of the `destructure_mir_constant` query. So in a follow-up we can remove the query and just move the query provider function directly into pretty printing (which is the last user).

cc `@rust-lang/clippy` there's a small functional change, but I think it is correct?
