In other words, enforce what was documented in #30626 (and also stop blaming it on LLVM, we have at least one Python script of our own).
Also, there is no Python later than 2.7 and there never will be.
This enables `*` in all type positions in doc searches, which I often
want in order to find functions that create or convert specific
types (e.g. `* -> vec`) but I don't actually know what kinds of input
they expect.
I actually started working on this because of #31598, but I've wanted it
several times when exploring new crates.
The issue was that the const evaluator was returning an error because
the feature flag const_indexing wasn't turned on. The error was then
reported as a bug.
Fixes#29914
Fix `read_link` to also be able to read the target of junctions on Windows.
Also the path returned should not include a NT namespace, and there were
some problems with permissions.
<sup>**context:** moving back to a layered approach to type checking.</sup>
It looks like they'd not ended up tightly coupled in the time one was owned by the other. Every instance outside of `FnCtxt.inh` was from an `InferCtxt` created and dropped in the same function body.
This conflicts slightly with #30652, but there too it looks like the `FulfillmentContext` is from an `InferCtxt` that is created and dropped within the same function body (across one call to a module-private function).
That said, I heard that the PR that originally moved `FulfillmentContext` into `InferCtxt` was big, which leaves me concerned that I'm missing something.

Ignores 82 rpass tests that use threads.
I took care to only ignore tests that call `thread::spawn`. Some tests, for example `issue-16597`, also do fail because of lack of threads support, but for other reasons.
With this PR, we're down to 49 failures.

This changes three ICEs to fatal errors.
I've grepped for `lang_item.*expect` and `\.expect.*lang` and didn't come up with any more. But, there could be more ICEs lurking.
I wasn't sure about a test because there already _is_ a cfail test for missing lang items, but it only checks one.
Relevant to (already closed) #31477#31480#31558.

This fixes#31512 for me.
A bit of explanation: I want to have `check_block_post(&mut self, &Context, &Block)` and `check_crate_post(&mut self, &Context, &Crate)` methods in both early and late lint passes. Ideally we'd have _post methods for all operations that walk, but this'll do for now.

I still need to add error code explanation test with this, but I can't figure out a way to generate the `.md` files in order to test example source codes.
Will fix#27328.
