777bb2f612 Auto merge of #84806 - Mark-Simulacrum:try-start-entry, r=cjgillot 
Streamline try_start code

This shifts some branches around and avoids interleaving parallel and
non-parallel versions of the function too much.

a1d7367429 Move iter_results to dyn FnMut rather than a generic 
This means that we're no longer generating the iteration/locking code for each
invocation site of iter_results, rather just once per query.

This is a 15% win in instruction counts when compiling the rustc_query_impl crate.

0019ca9141 Fix outdated crate names in compiler docs 
Changes `librustc_X` to `rustc_X`, only in documentation comments.
Plain code comments are left unchanged.

Also fix incorrect file paths.

It may also be useful in these cases,
and some CI configurations test without debug assertions.

441dc3640a Remove (lots of) dead code 
Found with https://github.com/est31/warnalyzer.

Dubious changes:
- Is anyone else using rustc_apfloat? I feel weird completely deleting
  x87 support.
- Maybe some of the dead code in rustc_data_structures, in case someone
  wants to use it in the future?
- Don't change rustc_serialize

  I plan to scrap most of the json module in the near future (see
  https://github.com/rust-lang/compiler-team/issues/418) and fixing the
  tests needed more work than I expected.

TODO: check if any of the comments on the deleted code should be kept.

Always run incremental_verify_ich when re-computing query results 
Issue #82920 showed that the kind of bugs caught by this flag have
soundness implications.

This causes performance regressions of up to 15.2% during incremental
compilation, but this is necessary to catch miscompilations caused by
bugs in query implementations.

097bc6a84f Auto merge of #81892 - jyn514:no-inline, r=cjgillot 
[experiment] remove `#[inline]` from rustc_query_system::plumbing

These functions have a ton of generic parameters and are instantiated
over and over again. Hopefully this will reduce binary bloat and speed
up bootstrapping times.
