Replace `_, _` with `..` in patterns

This is how https://github.com/rust-lang/rust/issues/33627 looks in action.

Looks especially nice in leftmost/rightmost positions `(first, ..)`/`(.., last)`.
I haven't touched libsyntax intentionally because the feature is still unstable.

43440a4a6e Rollup merge of #36212 - razielgn:updated-e0493-to-new-format, r=jonathandturner 
Updated e0493 to new format (+ bonus).

Part of #35233.
Fixes #35999.

r? @jonathandturner

I'm not satisfied with the bonus part, there has to be an easier way to reach into the `Drop`'s span implementation. I'm all ears. :)

[MIR] track Location in MirVisitor, combine Location

All the users of MirVisitor::visit_statement implement their own statement index tracking.  This PR move the tracking into MirVisitor itself.

Also, there were 2 separate implementations of Location that were identical.  This PR eliminates one of them.

Fix the invalidation of the MIR early exit cache

~~The #34307 introduced a cache for early exits in order to help with O(n*m) explosion of cleanup blocks but the cache is invalidated incorrectly and I can’t seem to figure out why (caching is hard!)~~

~~Remove the cache for now to fix the immediate correctness issue and worry about the performance later.~~

Cache invalidation got fixed.

Fixes #35737

Implement the `!` type

This implements the never type (`!`) and hides it behind the feature gate `#[feature(never_type)]`. With the feature gate off, things should build as normal (although some error messages may be different). With the gate on, `!` is usable as a type and diverging type variables (ie. types that are unconstrained by anything in the code) will default to `!` instead of `()`.

[MIR] Add explicit SetDiscriminant StatementKind for deaggregating enums

cc #35186

To deaggregate enums, we need to be able to explicitly set the discriminant.  This PR implements a new StatementKind that does that.

I think some of the places that have `panics!` now could maybe do something smarter.
