Split Bound index into Canonical and Bound
See [#t-types/trait-system-refactor > perf `async-closures/post-mono-higher-ranked-hang.rs`](https://rust-lang.zulipchat.com/#narrow/channel/364551-t-types.2Ftrait-system-refactor/topic/perf.20.60async-closures.2Fpost-mono-higher-ranked-hang.2Ers.60/with/541535613) for context
Things compile and tests pass, but not sure if this actually solves the perf issue (edit: it does). Opening up this to do a perf (and maybe crater) run.

Much of the compiler calls functions on Align projected from AbiAlign.
AbiAlign impls Deref to its inner Align, so we can simplify these away.
Also, it will minimize disruption when AbiAlign is removed.
For now, preserve usages that might resolve to PartialOrd or PartialEq,
as those have odd inference.
Rollup merge of #146667 - calebzulawski:simd-mono-lane-limit, r=lcnr,RalfJung2025-09-25T10:31:53+00:00Stuart CookZalathar@users.noreply.github.com2025-09-25T10:31:53+00:00urn:sha1:fab06469ee33664739620ede53ed18b8c3c40644
Add an attribute to check the number of lanes in a SIMD vector after monomorphization
Allows std::simd to drop the `LaneCount<N>: SupportedLaneCount` trait and maintain good error messages.
Also, extends rust-lang/rust#145967 by including spans in layout errors for all ADTs.

Add span for struct tail recursion limit error
Fixes rust-lang/rust#135629
Changes
1. Add span to RecursionLimitReached
2. Add ObligationCause parameter to struct_tail_raw
4. Update call sites to pass nearby ObligationCause or create one
5. Update affected .stderr
