This flag (counterintuitively) was removing the `GNU_STACK` ELF attribute, which caused the optimized `libLLVM.so` file to be flagged as having an executable stack on SELinux.

Move a const-prop-lint specific hack from mir interpret to const-prop-lint and make it fallible
fixes#109743
This hack didn't need to live in the mir interpreter. For const-prop-lint it is entirely correct to avoid doing any const prop if normalization fails at this stage. Most likely we couldn't const propagate anything anyway, and if revealing was needed (so opaque types were involved), we wouldn't want to be too smart and leak the hidden type anyway.
Don't collect return-position impl traits for documentation
#104889 modified the rustdoc ast collection step to use a HIR visitor, which more thoroughly walks the HIR tree. that means that we're going to encounter inner items (incl return-position impl traits and async fn opaque futures) that are not possible to document.
FIxes (but does not close due to being a beta regression) #109931

rustdoc: escape GAT args in more cases
Fixes#109488.
Previously we printed the *un*escaped form of GAT arguments not only when `f.alternate()` was true but *also* when we failed to compute the URL of the trait associated with the type projection, i.e. when `href(…)` returned an `Err(_)`.
In this PR the argument printing logic is entirely separate from the link resolution code above as it should be.
Further, we now only try to compute the URL if the HTML format was requested with `!f.alternate()`. Before, we would sometimes compute the `href` only to throw it away later.
Emit feature error for parenthesized generics in associated type bounds
We don't actually do AST->HIR lowering with some `-Zunpretty` flags, so it's not correct to just delay a bug instead of emitting a feature error.
Some diagnostics regressed because of the new errors, but oh well. 🤷Fixes#109898
Fix `non_exhaustive_omitted_patterns` lint span
Fixes#109837
`DUMMY_SP` was being passed as the span in many cases where we have a span available to use. This meant that the location of the violating pattern wasn't shown, or the list of un-covered variants

Pull some tuple variant fields out into their own struct
This is groundwork for adding more fields to those new structs, but I believe the change to be useful on its own.
r? `@Nilstrieb` but feel free to reroll for `compiler`
Remove `intercrate` and `mark_ambiguous` from `TypeRelation`
Fixes#109863
Pulls this logic into `super_combine_tys`, which has access to `InferCtxt` and takes a `ObligationEmittingRelation` -- both of which simplify the logic here.

Remove optimal xz settings from CI
This is a companion PR to rust-lang/promote-release#58, which moves the relevant optimal code to rust-lang/promote-release. As mentioned in the comments of that PR, this is expected to cut CI costs (and time, though predominantly felt on fast builders) and reduce wasted resources due to in-practice single-threaded compression not using the full 8+ vCPU builders we have available.
This probably shouldn't land before that PR + a simpleinfra change to enable the recompression of xz artifacts. But if it does land, it's just a matter of a few nightlies with slightly larger artifacts, so not a big deal.

OpenHarmony uses emulated TLS, which doesn't link properly when using
thread-local variables across crate boundaries with `-C prefer-dynamic`.
This PR makes thread_local! use pthreads directly instead.
rustdoc: make intra-doc link pass non-quadratic for repeated links
In the collect_intra_doc_links pass, links to a given item that occurred repeatedly were getting inserted into a `Vec<clean::ItemLink>` repeatedly. This led to n^2 behavior (where n = the number of pages generated), particularly for the intra-doc link on the `Into<U> for T where U: From<T>` blanket implementation, since that link appears on every single struct page.
Fixes#109851
Never consider int and float vars for `FnPtr` candidates
This solves a regression where `0.0.cmp()` was ambiguous when a custom trait with a `cmp` method was in scope.
For integers it shouldn't be a problem in practice so I wasn't able to add a test.
I'm not sure whether there could be more issues hidden in the shadows as mentioned in the issue, but this should at least fix the problematic regression immediately.
