fda3378e3f introduce negative_impls feature gate and document 
They used to be covered by `optin_builtin_traits` but negative impls
are now applicable to all traits, not just auto traits.

This also adds docs in the unstable book for the current state of auto traits.

Rollup merge of #70364 - petrochenkov:nofrustc, r=Centril 
resolve: Remove `rustc_attrs` as a standalone feature gate

Now it only gates specific built-in attributes.

So if you want to make a rustc attribute, make it a built-in (this was already the case in practice for some time).

Rollup merge of #70234 - anp:tracked-std-traits, r=Amanieu 
#[track_caller] on core::ops::{Index, IndexMut}.

Applies the attribute to `core::ops::Index(Mut)` and enough std internals to cover the [functions listed in "tier 1" in the original RFC](https://github.com/rust-lang/rfcs/blob/master/text/2091-inline-semantic.md#survey-of-panicking-standard-functions).

Split out from #69251 to allow separate assessment of perf impact.

To my knowledge, this is the last piece of implementing RFC 2091.

Rollup merge of #70077 - Aaron1011:feature/new-def-path-ident, r=petrochenkov 
Store idents for `DefPathData` into crate metadata

Previously, we threw away the `Span` associated with a definition's
identifier when we encoded crate metadata, causing us to lose location
and hygiene information.

We now store the identifier's `Span` in a side table, which gets encoded
into the crate metadata. When we decode items from the metadata, we
combine the name and span back into an `Ident`.

This improves the output of several tests, which previously had messages
suppressed due to dummy spans.

This is a prerequisite for #68686, since throwing away a `Span` means
that we lose hygiene information.

Rollup merge of #70283 - CDirkx:regression-test-70155, r=oli-obk 
Add regression test for #70155.

With #70166 merged, `RangeInclusive` now derives `PartialEq` and `Eq`, implementing structural equality and as a side effect the range is now usable with const generics, closing #70155.

As per [#70166 (comment)](https://github.com/rust-lang/rust/pull/70166#issuecomment-601872201) a test is added to avoid a change to the private fields or the equality implementation of the range from subtly reverting #70155.
