Add a proc-macro to derive HashStable in librustc dependencies
A second proc-macro is added to derive HashStable for crates librustc depends on.
This proc-macro HashStable_Generic (to bikeshed) allows to decouple code and some librustc's boilerplate.
Not everything is migrated, because `Span` and `TokenKind` require to be placed inside librustc.
Types using them stay there too.
Split out of #66279

Move process_configure_mod to rustc_parse
This removes the hack in favor of perhaps a less principled, but less painful, approach.
This also supports my work to decouple `Session` from librustc, as `ParseSess` currently has `Attribute` as "part" of it but after this PR will no longer do so.

Delay an `is_local_ever_initialized` call.
This commit moves the call after a `return` that almost always runs. It
speeds up the `unicode_normalization` benchmark by about 2%.

Support multiple revisions in `compiletest`
The `//[X]~` syntax filters errors for tests that are run across multiple cfgs with `// revisions:`. This commit extends that syntax to accept `//[X,Y]~`, which will match multiple cfgs to the same error annotation. This is functionally the same as writing two comments, `//[X]~` and `//[Y]~`, but can fit on a single line.
While refactoring `compiletest` to support this, I also uncovered a small bug that was causing an incremental test to always pass, despite no errors being emitted.

[mir-opt] asking `?`s in a more optimized fashion
This PR works towards https://github.com/rust-lang/rust/issues/66234 by providing two optimization passes meant to run in sequence:
- `SimplifyArmIdentity` which transforms something like:
```rust
_LOCAL_TMP = ((_LOCAL_1 as Variant ).FIELD: TY );
((_LOCAL_0 as Variant).FIELD: TY) = move _LOCAL_TMP;
discriminant(_LOCAL_0) = VAR_IDX;
```
into:
```rust
_LOCAL_0 = move _LOCAL_1
```
- `SimplifyBranchSame` which transforms `SwitchInt`s to identical basic blocks into a `goto` to the first reachable target.
Together, these are meant to simplify the following into just `res`:
```rust
match res {
Ok(x) => Ok(x),
Err(x) => Err(x),
}
```
It should be noted however that the desugaring of `?` includes a function call and so the first pass in this PR relies on inlining to substitute that function call for identity on `x`. Inlining requires `mir-opt-level=2` so this might not have any effect in perf-bot but let's find out.
r? @oli-obk -- This is WIP, but I'd appreciate feedback. :)

This test does not actually emit any warnings, since
`#![allow(warnings)]` was specified. `compiletest` was erroneously
ignoring `//~` tests and looking only for `//[X]~` ones. As a result of
the changes in the previous commit, we now look for `//~` comments in
incremental tests and expect them to appear in *all* revisions.

Aggregation of drive-by cosmetic changes for trait-upcasting PR
Cherry-picked from #60900.
As requested by @Centril (and @nikomatsakis, I believe).

This optimization depends on inlining for the identity
conversions introduced by the lowering of the `?`.
To take advantage of `SimplifyArmIdentity`, `-Z mir-opt-level=2`
is required because that triggers the inlining MIR optimization.

pnkfelix:issue-66568-ignore-reproducible-build-2-on-macos, r=alexcrichton
Ignore run-make reproducible-build-2 on Mac
Ignore run-make reproducible-build-2 on Mac (we already ignore it on Windows).
Until we can dedicate resources to fixing this properly, I think we are best off just ignoring this test on platforms/contexts where it does not matter as much.

rustc_metadata: Privatize more things
Continuation of https://github.com/rust-lang/rust/pull/66056.
The most notable change here is that `CrateMetadata` is moved from `cstore.rs` to `decoder.rs`.
Most of uses of `CrateMetadata` fields are in the decoder and uses of `root: CrateRoot` and other fields are so intertwined with each other that it would be hard to move a part of them into `cstore.rs` to privatize `CrateMetadata` fields, so we are going the other way round.
`cstore.rs` can probably be dismantled now, but I'll leave this to some other day.
Similarly, remaining `CrateMetadata` fields can be privatized by introducing some getter/setter methods, but not today.

rustdoc: fixes #64305: disable search field instead of hidding it
The result seems to be ok but I wasn't entirely sure how to get there. I tried to stay generic a bit but maybe it's not required at all.

Making ICEs and test them in incremental
This adds:
- A way to make the compiler ICE
- A way to check for ICE in `cfail` tests with `should-ice`
- A regression test for issue #65401
I am not sure the attribute added `should-ice` is the best for this job
