Fix the conflict problem between the diagnostics fixes of lint `unnecessary_qualification` and `unused_imports`
fixes #121331
For an `item` that triggers lint unnecessary_qualification, if the `use item` which imports this item is also trigger unused import, fixing the two lints at the same time may lead to the problem that the `item` cannot be found.
This PR will avoid reporting lint unnecessary_qualification when conflict occurs.

Michael Goulet: Don't issue feature error in resolver for f16/f128

Also rename `into_diagnostic_arg` as `into_diag_arg`, and
`NotIntoDiagnosticArg` as `NotInotDiagArg`.
|
|
It's the only diagnostic in the entire project that impls `Default`, and
the code is clearer without it.

Add asm goto support to `asm!`
Tracking issue: #119364
This PR implements asm-goto support, using the syntax described in "future possibilities" section of [RFC2873](https://rust-lang.github.io/rfcs/2873-inline-asm.html#asm-goto).
Currently I have only implemented the `label` part, not the `fallthrough` part (i.e. fallthrough is implicit). This doesn't reduce the expressive though, since you can use label-break to get arbitrary control flow or simply set a value and rely on jump threading optimisation to get the desired control flow. I can add that later if deemed necessary.

Remove `feed_local_def_id`
best reviewed commit by commit
Basically I returned `TyCtxtFeed` from `create_def` and then preserved that in the local caches
based on https://github.com/rust-lang/rust/pull/121084

Fix linting paths with qself in `unused_qualifications`
Fixes #121999
`resolve_qpath` ends up being called again with `qself` set to `None` to check trait items from fully qualified paths. To avoid this the lint is moved to a place that accounts for this already
https://github.com/rust-lang/rust/blob/96561a8fd134e8f2b205769a4fca03b392d9f484/compiler/rustc_resolve/src/late.rs#L4074-L4088

Not the dropping of the trailing `s` -- this type describes a single
diagnostic and its name should be singular.

`ParseSess` cleanups
The main change here is to rename all `ParseSess` values as `psess`. Plus a few other small cleanups.
r? `@wesleywiser`
|
|
Existing names for values of this type are `sess`, `parse_sess`,
`parse_session`, and `ps`. `sess` is particularly annoying because
that's also used for `Session` values, which are often co-located, and
it can be difficult to know which type a value named `sess` refers to.
(That annoyance is the main motivation for this change.) `psess` is nice
and short, which is good for a name used this much.
The commit also renames some `parse_sess_created` values as
`psess_created`.

Consider middle segments of paths in `unused_qualifications`
Currently `unused_qualifications` looks at the last segment of a path to see if it can be trimmed, this PR extends the check to the middle segments also
```rust
// currently linted
use std::env::args();
std::env::args(); // Removes `std::env::`
```
```rust
// newly linted
use std::env;
std::env::args(); // Removes `std::`
```
Paths with generics in them are now linted as long as the part being trimmed is before any generic args, e.g. it will now suggest trimming `std::vec::` from `std::vec::Vec<usize>`
Paths with any segments that are from an expansion are no longer linted
Fixes #100979
Fixes #96698

Improve renaming suggestion when item starts with underscore
Fixes https://github.com/rust-lang/rust/issues/121776.
It goes from:
```terminal
error[E0433]: failed to resolve: use of undeclared type `Foo`
--> src/foo.rs:6:13
|
6 | let _ = Foo::Bar;
| ^^^ use of undeclared type `Foo`
|
help: an enum with a similar name exists, consider changing it
|
1 | enum Foo {
| ~~~
```
to:
```terminal
error[E0433]: failed to resolve: use of undeclared type `Foo`
--> foo.rs:6:13
|
6 | let _ = Foo::Bar;
| ^^^ use of undeclared type `Foo`
|
help: an enum with a similar name exists, consider renaming `_Foo` into `Foo`
|
1 | enum Foo {
| ~~~
error: aborting due to 1 previous error
```
|
|
obvious what is actually suggested

Diagnostic renaming
Renaming various diagnostic types from `Diagnostic*` to `Diag*`. Part of https://github.com/rust-lang/compiler-team/issues/722. There are more to do but this is enough for one PR.

Fix issues in suggesting importing extern crate paths

Much better!
Note that this involves renaming (and updating the value of)
`DIAGNOSTIC_BUILDER` in clippy.
|
|
`Resolver::report_error` always emits (this commit makes that clearer),
so the `span_delayed_bug` is unnecessary.

Add newtypes for bool fields/params/return types
Fixed all the cases of this found with some simple searches for `*/ bool` and `bool /*`; probably many more
