Under the gate, `x @ Some(y)` is allowed.
This is subject to various restrictions for soundness.

Enable `loop` and `while` in constants behind a feature flag
This PR is an initial implementation of #52000 . It adds a `const_loop` feature gate, which allows `while` and `loop` expressions through both HIR and MIR const-checkers if enabled. `for` expressions remain forbidden by the HIR const-checker, since they desugar to a call to `IntoIterator::into_iter`, which will be rejected anyways.
`while` loops also require [`#![feature(const_if_match)]`](https://github.com/rust-lang/rust/pull/66507 ), since they have a conditional built into them. The diagnostics from the HIR const checker will suggest this to the user.

Revert stabilization of never type
Fixes https://github.com/rust-lang/rust/issues/66757
I decided to keep the separate `never-type-fallback` feature gate, but tried to otherwise revert https://github.com/rust-lang/rust/pull/65355 . Seemed pretty clean.

Auto merge of #65881 - anp:implicit-caller-location, r=eddyb,oli-obk
...
Implement #[track_caller] attribute. (RFC 2091 4/N)
Implements the `#[track_caller]` attribute in both const and codegen contexts.
The const implementation walks up the stack to find the nearest untracked callsite.
The codegen implementation adds an implicit argument to tracked function calls, and populates it with either a call to the previously-landed intrinsic or if the caller has `#[track_caller]` with a copy of the location passed to the current function.
Also includes a little cleanup and a few comments in the other caller location areas.
