Find codegen backends in more locations
* Search in the sysroot passed using `--sysroot` in addition to the default sysroot.
* Search for `librustc_codegen_$name.so` in addition to `librustc_codegen_$name-$release.so`.
This combined would allow putting `librustc_codegen_cranelift.so` in the right location of a sysroot passed using `--sysroot`.
- Add back `HirIdVec`, with a comment that it will soon be used.
- Add back `*_region` functions, with a comment they may soon be used.
- Remove `-Z borrowck_stats` completely. It didn't do anything.
- Remove `make_nop` completely.
- Add back `current_loc`, which is used by an out-of-tree tool.
- Fix style nits
- Remove `AtomicCell` with `cfg(parallel_compiler)` for consistency.
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.
Add `-Z unpretty` flags for the AST
Implements rust-lang/compiler-team#408.
Builds on #82269, but if that PR is rejected or stalls out, I can implement this without #82269.

Cleanup `PpMode` and friends
This PR:
- Separates `PpSourceMode` and `PpHirMode` to remove invalid states
- Renames the variant to remove the redundant `Ppm` prefix
- Adds basic documentation for the different pretty-print modes
- Cleanups some code to make it more idiomatic
Not sure if this is actually useful, but it looks cleaner to me.

rustdoc: Support argument files
Factors out the `rustc_driver` logic that handles argument files so that rustdoc supports them as well, e.g.:
rustdoc `@argfile`
This is needed to be able to generate docs for projects that already use argument files when compiling them, e.g. projects that pass a huge number of `--cfg` arguments.
The feature was stabilized for `rustc` in #66172.

Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.
Also, improve alignment of columns.
Fix --pretty=expanded with --remap-path-prefix
Per https://github.com/rust-lang/rust/issues/80832, using
--pretty=expanded and --remap-path-prefix results in an ICE.
This is becasue the session source files table is stored in remapped
form, whereas --pretty-expanded looks up unremapped files. This remaps
the path prefixes before lookup.
~~There don't appear to be any existing tests for --pretty=expanded; I'll look into
adding some.~~ Never mind, found the pretty tests.
Fixes#80832
