2020-03-26Rollup merge of #70411 - ogoffart:fix-62691, r=eddybMazdak Farrokhzad-0/+7
Fix for #62691: use the largest niche across all fields fixes #62691 (The second commit is a small optimization but it makes the code less pretty and i don't know if it is worth it.)

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.

Fix smaller issues with invalid placeholder type errors Follow up to #70294. - Fix placement of suggested generic param when bounds are present. - Reduce error duplication for invalid placeholder types in `fn` types. r? @Centril
2020-03-25Rollup merge of #70364 - petrochenkov:nofrustc, r=CentrilMazdak Farrokhzad-20/+79
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).

Miri: move ModifiedStatic to ConstEval errors Also generally adjust terminology from "static" to "global" where appropriate (to avoid confusion with specifically `static` items).
2020-03-24Rollup merge of #70234 - anp:tracked-std-traits, r=AmanieuMazdak Farrokhzad-0/+22
#[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. Tracking issue: https://github.com/rust-lang/rust/issues/47809

2020-03-24Rollup merge of #70077 - Aaron1011:feature/new-def-path-ident, r=petrochenkovMazdak Farrokhzad-37/+292
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.
