Warn when using panic-strategy abort for proc-macro crates
See https://github.com/rust-lang/rust/issues/82320, this simply warns for now as that seems like the best step that can be immediately taken (opposed to straight up rejecting or ignoring)
Migrate `rustc_lint` lint diagnostics
Part 2 of [Migrate `rustc_lint` errors to `SessionDiagnostic`](https://github.com/rust-lang/rust/pull/100776)
r? `@davidtwco`
# TODO
- [x] Refactor some lints manually implementing `DecorateLint` to use `Option<Subdiagnostic>`.
- [x] Add `#[rustc_lint_diagnostics]` to lint functions in `context.rs`.
- [x] Migrate `hidden_unicode_codepoints.rs`.
- [x] Migrate `UnsafeCode` in `builtin.rs`.
- [x] Migrate the rest of `builtin.rs`.
remove unreachable error code `E0490`
AFAIK, the untested and undocumented error code `E0490` is now unreachable, it was from the days of the original borrow checker.

Move autoderef to `rustc_hir_analysis`
Not sure if this is a change we actually want, but autoderef really is only (functionally) used by `rustc_hir_analysis` and `rustc_hir_typeck`, so it probably should live there.
Instead, implement a separate autoderef helper in `TypeErrCtxt` for the one use-case that goes against the ordering of the crate graph..
Migrate mir_build diagnostics 2 of 3
The first three commits are fairly boring, however I've made some changes to the output of the match checking diagnostics.
Recover from where clauses placed before tuple struct bodies
Open to any suggestions regarding the phrasing of the diagnostic.
Fixes#100790.

Migrate `codegen_ssa` to diagnostics structs - [Part 3]
Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates:
1. [`rustc_middle::mir::interpret::InterpError`](b6097f2e1b/compiler/rustc_middle/src/mir/interpret/error.rs (L475)): I saw `rustc_middle` is unassigned, I am open to take this work.
2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](9a31b3cdda) of this PR, but would like to know the team's preference on how we should keep replacing the other macros:
2.1. Update macros to expect a `Diagnostic`
2.2. Remove macros and expand the code on each use.
See [some examples of the different options in this experimental commit](64aee83e80)

Migrating rustc_infer to session diagnostics (part 3)
``@rustbot`` label +A-translation
r? rust-lang/diagnostics
cc https://github.com/rust-lang/rust/issues/100717
Seems like a part of static_impl_trait.rs emits suggestions in a loop, and note.rs needs to have two instances of the same subdiagnostic, so these will need to wait until we have eager translation/list support.
Other than that, there is only error_reporting/mod.rs left to migrate.
Small fixes for --crate-type staticlib
The first commit doesn't have an effect until we start translating error messages. The second commit fixes potential linker errors when combining `--crate-type staticlib` with another crate type and I think `-Cprefer-dynamic`.
Only include metadata for non-dynamic libraries in rustc-dev
The actual object code should be linked from librustc_driver.so, which is still included in rustc-dev. This saves on download time and disk usage.
Fixes https://github.com/rust-lang/rust/issues/103538
