cleanup: Remove compile-fail-fulldeps directory again
It was already removed once in https://github.com/rust-lang/rust/pull/56444, but was partially resurrected by rebase of some other PR.
Do not complain about non-existing fields after parse recovery
When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.
Fix#57361.
consistent naming for Rhs type parameter in libcore/ops
Rename RHS type parameter occurrences RHS->Rhs to make it consistent throughout files and follow naming conventions.
Point at coercion reason for `if` expressions without else clause if caused by return type
```
error[E0317]: if may be missing an else clause

Fixes for the generator transform
* Moves cleanup annotations in pretty printed MIR so that they can be tested
* Correctly determines which drops are in cleanup blocks when elaborating generator drops
* Use the correct state for poisoning a generator
Closes#58892
Introduce assembly tests suite
The change introduces a new test suite - **Assembly** tests. The motivation behind this is an ability to perform end-to-end codegen testing with LLVM backend. Turned out, NVPTX backend sometimes missing common Rust features (`i128` and libcalls in the past, and still full atomics support) due to different reasons.
Prior to this change, basic NVPTX assembly tests were implemented within `run-make` suite. Now, it's easier to write additional and maintain existing tests for the target.

cc @eddyb I adjusted mangling scheme expectation, so there is no need to change the tests for #57967
Keep last redundant linker flag, not first
When a library (L1) is passed to the linker multiple times, this is sometimes purposeful: there might be several other libraries in the linker command (L2 and L3) that all depend on L1. You'd end up with a (simplified) linker command that looks like:
```
-l2 -l1 -l3 -l1
```
With the previous behavior, when rustc encountered a redundant library, it would keep the first instance, and remove the later ones, resulting in:
```
-l2 -l1 -l3
```
This can cause a linker error, because on some platforms (e.g. Linux), the linker will only include symbols from L1 that are needed *at the point it's referenced in the command line*. So if L3 depends on additional symbols from L1, which aren't needed by L2, the linker won't know to include them, and you'll end up with "undefined symbols" errors.
A better behavior is to keep the *last* instance of the library:
```
-l2 -l3 -l1
```
This ensures that all "downstream" libraries have been included in the linker command before the "upstream" library is referenced.
Fixes rust-lang#47989
extra testing of how NLL handles wildcard type `_`
test that wildcard type `_` is not duplicated by `type Foo<X> = (X, X);` and potentially instantiated at different types when used in type ascriptions in let bindings.
(NLL's handling of this for the type ascription *expression form* is currently broken, or at least differs from what AST-borrowck does. I'll file a separate bug about that. Its not something critical to address since that expression is guarded by `#![feature(type_ascription)]`.)

overhaul intra-doc-link ambiguity warning
Fixes#52784.
- Makes the warning part of the `intra_doc_link_resolution_failure`
lint.
- Tightens the span to just the ambiguous link.
- Reports ambiguities across all three namespaces.
- Uses structured suggestions for disambiguation.
- Adds a test for the warnings.

Filter ui revision tests
Updates UI test output filtering to also filter away test annotations for revisions:
Previously filtered: //~ ERROR [XXXX]
Now also filters: //[revision]~ ERROR [XXXX]
I reckon, if we have the one, we should have the other for consistency, its lack was probably an oversight (the existence of revision testing is not really well documented...)
