- Hide common linker output behind `linker-info`
- Add tests
- Account for different capitalization on windows-gnu when removing
  "warning" prefix
- Add some more comments
- Add macOS deployment-target test
- Ignore linker warnings from trying to statically link glibc

  I don't know what's going on in `nofile-limit.rs` but I want no part
  of it.

- Use a fake linker so tests are platform-independent

Make format-like macro calls look similar to what `cargo fmt` does automatically - remove trailing commas. When removing a comma, I also inlined some variables for consistency and clarity.

Keys and values now must be `Copy` due to erasing.

The derived version is equivalent to the hand-written version.

The latter is a new module.

As well as the code motion, some other changes were required.
- `QueryJobId` methods became free functions so they could move while
  `QueryJobId` itself stayed put. This was so `QueryMap` and
  `QueryJobInfo` could be moved.
- Some visibilities in `rustc_query_system` required changing.
- `collect_active_jobs_from_all_queries` is no longer required in `trait
  QueryContext`.

Because all uses are now in `rustc_query_impl`. This was made possible
by the previous commit. Less code in `rustc_middle`, hooray.

From `rustc_query_system::query::job` to `rustc_query_impl::job`.

…rmal attribute logic instead of special cased checks

try enabling `linker-messages` by default again

- Split out `linker-info` from `linker-messages`
- Make `linker-messages` warn-by-default; keep `linker-info` deny-by-default

Helps with rust-lang#136096.

Don't ICE on layout error in vtable computation

Fixes rust-lang#152030.

Note: I'm including a more general testcase that doesn't use the feature in the original report, but only reproduces with debuginfo disabled. Does it make sense to also include the original testcase?

Move more query system code

Towards the goal of eliminating `rustc_query_system`, this commit moves some code from `rustc_query_system` to `rustc_middle` and `rustc_query_impl`, and from `rustc_middle` to `rustc_query_impl`.

Reenable a GCI+mGCA+GCPT test case

The GCI+mGCA+GCPT test case can now be made to work with the necessary features and tweaks.

Support ADT types in type info reflection

Tracking issue: rust-lang#146922 `#![feature(type_info)]`

This PR supports ADT types for feature `type_info` reflection.
(It's still a draft PR, with implementation in progress)

Note that this PR does not take SemVer into consideration (I left a FIXME comment). As discussed earlier ([comment](rust-lang#146923 (comment))), this requires further discussion. However, I hope we could get an initial implementation to land first, so we can start playing with it.

### Progress / Checklist

- [x] Struct support.
- [x] Enum
- [x] Union

style: remove unneeded trailing commas

Make format-like macro calls look similar to what `cargo fmt` does automatically - remove trailing commas. When removing a comma, I also inlined some variables for consistency and clarity.

I'm working on a [clippy lint](rust-lang/rust-clippy#16530) to make this process automatic.

BikeshedGuaranteedNoDrop trait: add comments indicating that it can be observed on stable

Not sure if that's worth it, maybe this goes without saying for all these builtin traits?
