Indicate origin of where type parameter for uninferred types
Based on #65951 (which is not merge yet), fixes #67277.
This PR improves a little the diagnostic for code like:
```
async fn foo() {
bar().await;
}
async fn bar<T>() -> () {}
```
by showing:
```
error[E0698]: type inside `async fn` body must be known in this context
--> unresolved_type_param.rs:9:5
|
9 | bar().await;
| ^^^ cannot infer type for type parameter `T` declared on the function `bar`
|
...
```
(The
```
declared on the function `bar`
```
part is new)
A small side note: `Vec` and `slice` seem to resist this change, because querying `item_name()` panics, and `get_opt_name()` returns `None`.

This reverts commit 3ed3b8bb7b100afecf7d5f52eafbb70fec27f537, reversing
changes made to 99b89533d4cdf7682ea4054ad0ee36c351d05df1.
We will reland a similar patch at a future date but for now we should get a nightly
released in a few hours with the parallel patch, so this should be
reverted to make sure that the next nightly is not parallel-enabled.
|
|
This also removes the unused NO_PARALLEL_COMPILER flag; if we want that
functionality we can readd it but this makes sure we really are parallel
everywhere.
This also patches a test that has differing output in the parallel case
(hopefully deterministically so!).

|
This reverts commit 8f6197f39f7d468dfc5b2bd41dae4769992a2f83.

Include a span in more `expected...found` notes
In most places, we use a span when emitting `expected...found` errors.
However, there were a couple of places where we didn't use any span,
resulting in hard-to-interpret error messages.
This commit attaches the relevant span to these notes, and additionally
switches over to using `note_expected_found` instead of manually
formatting the message

Make `process_obligations()` greedier.
`process_obligations()` adds new nodes, but it does not process these
new nodes until the next time it is called.
This commit changes it so that it does process these new nodes within
the same call. This change reduces the number of calls to
`process_obligations()` required to complete processing, sometimes
giving significant speed-ups.
The change required some changes to tests.
- The output of `cycle-cache-err-60010.rs` is slightly different.
- The unit tests required extra cases to handle the earlier processing
of the added nodes. I mostly did these in the simplest possible way,
by making the added nodes be ignored, thus giving outcomes the same as
with the old behaviour. But I changed `success_in_grandchildren()`
more extensively so that some obligations are completed earlier than
they used to be.

Issue #22750
The error reporting for E0277 (the trait `X` is not implemented for `Foo`)
now checks whether `Foo` implements a trait with the same path as `X`,
which probably means that the programmer wanted to actually use only one
version of the trait `X` instead of the two.

Aggregation of drive-by cosmetic changes for trait-upcasting PR
Cherry-picked from #60900.
As requested by @Centril (and @nikomatsakis, I believe).

Specific labels when referring to "expected" and "found" types

Also remove `never_type` the feature-gate test.

When there are multiple implementors for the same trait that is present
in an unmet binding, modify the E0277 error to refer to the parent
obligation and verify whether borrowing the argument being passed in
would satisfy the unmet bound. If it would, suggest it.

consistent handling of missing sysroot spans
Due to https://github.com/rust-lang/rust/issues/53081, sysroot spans (pointing to code in libcore/libstd/...) fails to print on some x86 runners. This consolidates the ignore directives for that and references the relevant issue.
I also did that for the generated derive-error-span tests -- but there the script and the tests were not entirely in sync any more since https://github.com/rust-lang/rust/pull/64151. Cc @estebank @varkor

Point at the span for the definition of ADTs internal to the current
crate.
Look at the leading char of the ident to determine whether we're
expecting a likely fn or any of a fn, a tuple struct or a tuple variant.
Turn fn `add_typo_suggestion` into a `Resolver` method.

Add test for rejecting `trait A: B1 = B2;`.
Also test rejection of `trait A: = B;`.
