Suggest to use . instead of :: when accessing a method of an object

make `error_reported` check for delayed bugs
Fixes #104768
`error_reported()` was only checking if there were errors emitted, not for `delay_bug`s which can also be a source of `ErrorGuaranteed`. I assume the same is true of `lint_err_count` but i dont know

Use `as_deref` in compiler (but only where it makes sense)
This simplifies some code :3
(there are some changes that are not exacly `as_deref`, but more like "clever `Option`/`Result` method use")

Add a detailed note for missing comma typo w/ FRU syntax
Thanks to `@pierwill` for working on this with me!
Fixes #104373, perhaps `@alice-i-cecile` can comment on the new error for the example provided on that issue -- feedback is welcome.

Use `IsTerminal` in place of `atty`
In any crate that can use nightly features, use `IsTerminal` rather than
`atty`:
- Use `IsTerminal` in `rustc_errors`
- Use `IsTerminal` in `rustc_driver`
- Use `IsTerminal` in `rustc_log`
- Use `IsTerminal` in `librustdoc`

Don't print full paths in overlap errors
We don't print the full path in other diagnostics -- I don't think it particularly helps with the error message. I also delayed the printing until actually needing to render the error message.

implement binding_shadows
migrate till self-in-generic-param-default
use braces in fluent message as suggested by @compiler-errors.
to fix lock file issue reported by CI
migrate 'unreachable label' error
run formatter
name the variables correctly in fluent file
SessionDiagnostic -> Diagnostic
test "pattern/pat-tuple-field-count-cross.rs" passed
test "resolve/bad-env-capture2.rs" passed
test "enum/enum-in-scope.rs" and other depended on "resolve_binding_shadows_something_unacceptable" should be passed now.
fix crash errors while running test-suite. there might be more.
then_some(..) suits better here.
all tests passed
convert TraitImpl and InvalidAsm. TraitImpl is buggy yet. will fix after receiving help from Zulip
migrate "Ralative-2018"
migrate "ancestor only"
migrate "expected found"
migrate "Indeterminate"
migrate "module only"
revert to the older implementation for now. since this is failing at the moment.
follow the convension for fluent variable
order the diag attribute as suggested in review comment
fix merge error. migrate trait-impl-duplicate

Display help message when fluent arg was referenced incorrectly
The fluent argument syntax is a little special and easy to get wrong, so we emit a small help message when someone gets it wrong.
Example:
```
parser_mismatched_closing_delimiter = mismatched closing delimiter: `${delimiter}`
```
panics with
```
thread 'rustc' panicked at 'Encountered errors while formatting message for `parser_mismatched_closing_delimiter`
help: Argument `delimiter` exists but was not referenced correctly. Try using `{$delimiter}` instead
attr: `None`
args: `FluentArgs([("delimiter", String("}"))])`
errors: `[ResolverError(Reference(Message { id: "delimiter", attribute: None }))]`', compiler/rustc_errors/src/translation.rs:123:21
```
fixes #103539

Some diagnostic-related nits
1. Use `&mut Diagnostic` instead of `&mut DiagnosticBuilder<'_, T>`
2. Make `diag.span_suggestions` take an `IntoIterator` instead of `Iterator`, just to remove some `.into_iter` calls on the caller.
idk if I should add a lint to make sure people use `&mut Diagnostic` instead of `&mut DiagnosticBuilder<'_, T>` in cases where we're just, e.g., adding subdiagnostics to the diagnostic... maybe a followup.

Migrate `codegen_ssa` to diagnostics structs - [Part 2]
Completes migrating `link.rs` in `codegen_ssa` module.

Port `dead_code` lints to be translatable.
This adds an additional comma to lists with three or more items, to be consistent with list formatters like `icu4x`.

Track where diagnostics were created.
This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`.
For example, the following code...
```rust
struct A;
struct B;
fn main(){
let _: A = B;
}
```
...now emits the following error message:
```
error[E0308]: mismatched types
--> src\main.rs:5:16
|
5 | let _: A = B;
| - ^ expected struct `A`, found struct `B`
| |
| expected due to this
-Ztrack-diagnostics: created at compiler\rustc_infer\src\infer\error_reporting\mod.rs:2275:31
```

This allows porting uses of span_suggestions() to diagnostic structs.
Doesn't work for multipart_suggestions() because the rank would be
reversed - the struct would specify multiple spans, each of which has
multiple possible replacements, while multipart_suggestions() creates
multiple possible replacements, each with multiple spans.
