Do not propose to simplify a not expression coming from a macro

Add RANLIB_x86_64_unknown_illumos env for dist-x86_64-illumos dockerfile
close https://github.com/rust-lang/cc-rs/issues/798
We already set `AR_x86_64_unknown_illumos` in the dockerfile. So it is reasonable to set the `RANLIB_x86_64_unknown_illumos`.
Limit the number of parallel link jobs during LLVM build for mingw.
This PR is an attempt to unblock https://github.com/rust-lang/rust/pull/108355, which keeps failing while trying to link various LLVM artifacts on mingw runners. It looks like doing too many linking jobs might put too much load on the system? (Although I don't understand why the jobs are only failing for #108355 while they seem to pass for others)
r? infra-ci
While we don't use GCC for the LLVM build, we do use its libstdc++,
and there has been an std::optional ABI break in this version.
This makes the libLLVM.so for LLVM 16 ABI-incompatible with newer
libstdc++ versions, which we use on all other builders, and which
download-ci-llvm users are likely to use.
Do not propose to remove `async move` if variables are captured by ref
Fixes#10482

a general type system cleanup
removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.
changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.
also removes some other small - and imo unnecessary - helpers.

Only clear written-to locals in ConstProp
This aims to revert the regression in https://github.com/rust-lang/rust/pull/108872
Clearing all locals at the end of each bb is very costly.
This PR goes back to the original implementation of recording which locals are modified.

Really dogfood clippy
The dogfood success condition was inverted in `tests/dogfood.rs`:
```rust
assert!(!failed_packages.is_empty(), …);
```
while instead the `failed_packages` collection must be empty:
```rust
assert!(failed_packages.is_empty(), …);
```
And indeed, several clippy lint source files were not clean and had to be fixed in the process.

Use uninit checking from rustc
rustc has proper heuristics for actually checking whether a type allows being left uninitialized (by asking CTFE). We can now use this for our helper instead of rolling our own bad version with false positives.
I added this in rustc in rust-lang/rust#108669
Fix#10407

Make local query providers receive local keys
When a query is marked `separate_provide_extern`, we can map a query key to a "local" form of the key, e.g. `DefId` -> `LocalDefId`. This simplifies a ton of code which either has to assert or use something like `expect_local` to assert that the query key is local.

Only implement Fn* traits for extern "Rust" safe function pointers and items
Since calling the function via an `Fn` trait will assume `extern "Rust"` ABI and not do any safety checks, only safe `extern "Rust"` function can implement the `Fn` traits. This syncs the logic between the old solver and the new solver.
r? `@compiler-errors`
Constrain const vars to error if const types are mismatched
When equating two consts of different types, if either are const variables, constrain them to the correct const error kind.
This helps us avoid "successfully" matching a const against an impl signature but leaving unconstrained const vars, which will lead to incremental ICEs when we call const-eval queries during const projection.
Fixes#109296
The second commit in the stack fixes a regression in the first commit where we end up mentioning `[const error]` in an impl overlap error message. I think the error message changes for the better, but I could implement alternative strategies to avoid this without delaying the overlap error message...

Drop all messages in bounded channel when destroying the last receiver
Fixes#107466 by splitting the `disconnect` function for receivers/transmitters and dropping all messages in `disconnect_receivers` like the unbounded channel does. Since all receivers must be dropped before the channel is, the messages will already be discarded at that point, so the `Drop` implementation for the channel can be removed.

Windows: make `Command` prefer non-verbatim paths
When spawning Commands, the path we use can end up being queried using `env::current_exe` (or the equivalent in other languages). Not all applications handle these paths properly therefore we should have a stronger preference for non-verbatim paths when spawning processes.
rustc has proper heuristics for actually checking whether a type allows
being left uninitialized (by asking CTFE). We can now use this for our
helper instead of rolling our own bad version with false positives.
