Move `IntoDiagnostic` conformance for `TargetDataLayoutErrors` into `rustc_errors`
Addressed this suggestion https://github.com/rust-lang/rust/pull/101558#issuecomment-1243830009.
This way we comply with the Coherence rule given that `IntoDiagnostic` trait is defined in `rustc_errors`, and almost all other crates depend on it.
In match guards, irrefutable prefixes might use the bindings created
by the match pattern. Ideally, we check for this, but we can do the
next best thing and just not lint for irrefutable prefixes in match
guards.
replace ReErased with fresh region vars in opaque types

rustdoc: don't ICE on `TyKind::Typeof`
Fixes#102986
I'm not sure why rustdoc started seeing `TyKind::Typeof` all of a sudden (the code being editted was last touched 3 months ago), probably something to do with error recovery? idk.
Add suggestion to the "missing native library" error
If we fail to locate a native library that we are linking with, it could be the case the user entered a complete file name like `foo.lib` or `libfoo.a` when we expect them to simply provide `foo`.
In this situation, we now detect that case and suggest the user only provide the library name itself.
The two items it was really intended to target were the buttons, and those
both need to have the style set directly on them anyway because the buttons
are both child elements of wrappers.

I think that #102845 caused #102933. Depending on the order that we elaborate these existential projection predicates, there's no guarantee that they'll be sorted by def id, which is what is failing the assertion in the issue.

openbsd: don't reallocate a guard page on the stack.
the kernel currently enforce that a stack is immutable. calling mmap(2) or mprotect(2) to change it will result in EPERM, which generate a panic!().
so just do like for Linux, and trust the kernel to do the right thing.
