f9dfb6e32f Rollup merge of #103544 - Nilstrieb:no-recovery-pls, r=compiler-errors 
Add flag to forbid recovery in the parser

To start the effort of fixing #103534, this adds a new flag to the parser, which forbids the parser from doing recovery, which it shouldn't do in macros.

This doesn't add any new checks for recoveries yet and is just here to bikeshed the names for the functions here before doing more.

rustc_metadata: Add struct and variant constructors to module children at encoding time

instead of decoding time.

Continuation of https://github.com/rust-lang/rust/pull/95899.
The last time it caused some ICEs from generator use, but not everything seems ok.

16e74c78a1 Rollup merge of #103255 - oli-obk:opaque_wrong_eq_relation, r=compiler-errors 
Clean up hidden type registration

work on https://github.com/rust-lang/rust/issues/101186

Actually passing down the relation and using it instead of `eq` for the hidden type comparison has *no* effect whatsoever and allows for no further improvements at the call sites. I decided the increased complexity was not worth it and thus did not include that change in this PR.

9dd3d29ec8 Auto merge of #103601 - compiler-errors:no-opaque-probe-in-nll-relate, r=oli-obk 
Remove `commit_if_ok` probe from NLL type relation

It was not really necessary to add the `commit_if_ok` in #100092 -- I added it to protect us against weird inference error messages due to recursive RPIT calls, but we are always on the error path when this happens anyways, and I can't come up with an example that makes this manifest.

Fixes #103599

r? `@oli-obk` since you reviewed #100092, feel free to re-roll.

🅱️ 📢  beta-nominating this since it's on beta (which forks in ~a week~ two days 😨) -- worst case we could revert the original PR on beta and land this on nightly, to give it some extra soak time...

7c6345d175 Allow use of -Clto=thin with -Ccodegen-units=1 in general 
The current logic to ignore ThinLTO when `-Ccodegen-units=1` makes sense
for local ThinLTO but even in this scenario, a user may still want
(non-local) ThinLTO for the purpose of optimizing dependencies into the
final crate which is being compiled with 1 CGU.

The previous behavior was even more confusing because if you were
generating a binary (`--emit=link`), then you would get ThinLTO but if
you asked for LLVM IR or bytecode, then it would silently change to
using regular LTO.

With this change, we only override the defaults for local ThinLTO if you
ask for a single output such as LLVM IR or bytecode and in all other
cases honor the requested LTO setting.

Revert "Unify tcx.constness and param env constness checks"

Too much of a perf regression https://github.com/rust-lang/rust/pull/102975#issuecomment-1282702513, and an attempt in #103263 didn't fix it except for just a tiny bit.

This change isn't really needed (see https://github.com/rust-lang/rust/pull/102830#issuecomment-1272514096), so this should be an easy revert.

Remove `rustc_driver::set_sigpipe_handler()`

Its usage was removed in https://github.com/rust-lang/rust/pull/102587 and https://github.com/rust-lang/rust/pull/103495, so we do not need to keep it around any longer. According to [preliminary input](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Find.20.60rustc_driver.60.20dependent.20projects.3F/near/304490764), we do not need to worry about any deprecation cycle for this explicitly unstable API, and can just straight up remove it.

Diagnostic derives: allow specifying multiple alternative suggestions

This allows porting `span_suggestions()` to diagnostic structs.

Doesn't work for `multipart_suggestions()` because the rank would be reversed - the struct would specify multiple spans, each of which has multiple possible replacements, while `multipart_suggestions()` creates multiple possible replacements, each with multiple spans.
