Since they are unlikely to fail and are almost never going to fail
except with bootstrap changes (which would be tested locally anyway) it
makes sense to run these tests close to last.
Refactor: Rename ExistentialPredicate::cmp to ExistentialPredicate::stable_cmp
See https://github.com/rust-lang/rust/pull/51276#discussion_r193549404 for
rationale.
Because stable_cmp takes three arguments and Ord::cmp takes two, I am confident that there is no shadowing happening here.

Removed various update-reference and update-all-references scripts
A PR that addresses #50853 changes that made `update-reference` and `update-all-references` scripts obsolete.
Improve core::task::TaskObj
- Rename `UnsafePoll` to `UnsafeTask` to avoid confusion with `Poll`
- Rename `TaskObj::from_poll_task()` to `TaskObj::new()`
- Rename `TaskObj`'s `poll` and `drop` fields to `poll_fn` and `drop_fn`
- Implement `Future` for `TaskObj`. Reason: It's a custom trait object for a future, so it should implement future
- Remove `unsafe impl Sync` for `TaskObj`. I don't think we need it. Was this safe? `UnsafeTask` only requires to implement `Send`

Make parse_seq_to_end and parse_path public
(see SergioBenitez/Rocket#660, rust-lang/rust#51265)
Rocket currently uses `parse_seq_to_end` and `parse_path` in its codegen macros. Assuming I tested correctly, this is the minimal set of methods that are currently necessary to build Rocket again. I would be happy to add documentation of this and Rocket's other usages, if desired.
Fix for $crate var normalization in proc macro for externally defined macros
Fixes#51331, a bug that has existed in at least *some* form for a year and a half.
The PR includes the addition of a `fold_qpath` method to `syntax::fold::Folder`. Overriding this method is useful for folds that modify paths in a way that invalidates indices (insertion or removal of a component), as it provides the opportunity to update `qself.position` in `<A as B>::C` paths. I added it because the bugfix is messy without it.
(unfortunately, grepping around the codebase, I did not see anything else that could use it.)
Make span_fatal and parse_block public
span_fatal and parse_block were made private in #51265. These methods are used in stainless.

[futures] add a few blanket impls to std
these were defined in the futures crate, but with the core definitions moving to std these would need to move too.
