Avoid ICE when referencing desugared local binding in borrow error
To avoid leaking the names of local bindings from expressions like for loops, #60984 explicitly ignored them, but an assertion that `LocalKind::Var` *must* have a name would trigger an ICE.
Before this change, the binding generated by desugaring the for loop would leak into the diagnostic (#63027):
```
error[E0515]: cannot return value referencing local variable `__next`
--> return-local-binding-from-desugaring.rs:LL:CC
|
LL | for ref x in xs {
| ----- `__next` is borrowed here
...
LL | result
| ^^^^^^ returns a value referencing data owned by the current function
```
Ideally `LocalKind` would carry more information to more accurately explain the problem, but for now, in order to avoid the ICE (fix#63026), we accept `LocalKind::Var` without a name and produce the following output:
```
error[E0515]: cannot return value referencing local binding
--> $DIR/return-local-binding-from-desugaring.rs:30:5
|
LL | for ref x in xs {
| -- local binding introduced here
...
LL | result
| ^^^^^^ returns a value referencing data owned by the current function
```
bump crossbeam-epoch dependency
The new crossbeam-epoch release depends on a memoffset with a whole bunch of soundness holes fixed.
The old memoffset is still indirectly depended on (at least) by rustc-rayon, though -- a crate that looks rather unmaintained (no change in more than a year).
Implement RFC 2707 + Parser recovery for range patterns
Implement https://github.com/rust-lang/rfcs/pull/2707.
- Add a new basic syntactic pattern form `ast::PatKind::Rest` (parsed as `..` or `DOTDOT`) and simplify `ast::PatKind::{Slice, Tuple, TupleStruct}` as a result.
- Lower `ast::PatKind::Rest` in combination with the aforementioned `PatKind` variants as well as `PatKind::Ident`. The HIR remains unchanged for now (may be advisable to make slight adjustments later).
- Refactor `parser.rs` wrt. parsing sequences and lists of things in the process.
- Add parser recovery for range patterns of form `X..`, `X..=`, `X...`, `..Y`, `..=Y`, and `...Y`.
This should make it easy to actually support these patterns semantically later if we so desire.
