<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.
Search results use the mapping found in `ItemType::to_static_str` for
the identifier, which could not be found on the page in the case of
associated items.
Tools which rely on DWARF for generating code coverage report, don't generate accurate numbers on test builds. For instance, [this sample main](757bdbf388/src/main.rs) returns [100% coverage](https://coveralls.io/builds/4940156/source?filename=main.rs) when [kcov](https://github.com/SimonKagstrom/kcov/) runs.
With @pnkfelix 's great help, we could narrow down the issue: The linker strips unused function during phase 6. Here's a patch which stops stripping when someone calls `rustc --test $ARGS`. @pnkfelix wasn't sure if we should add a new flag, or just use --test. What do you think @alexcrichton ?
Also, I'm not too sure: where is the best place to add a test for this addition?
Thanks for the help!
