The LLD + ThinLTO __morestack bug has been fixed in 12.0.1, so
we can now update our clang version. This also means that we no
longer need to build Python 2.
only check cg defaults wf once instantiated
the previous fixmes here didn't make too much sense as I didn't yet fully understand the code further below.
That code only runs if the predicates using our generic param default are fully concrete after substituting our default, which never happens if our default is generic.

Remove `missing_docs` lint on private 2.0 macros
798baebde1/compiler/rustc_lint/src/builtin.rs (L573-L584)
This code is the source of #57569. The problem is subtle, so let me point it out. This code makes the mistake of assuming that all of the macros in `krate.exported_macros` are exported.
...Yeah. For some historical reason, all `macro` macros are marked as exported, regardless of whether they actually are, which is dreadfully confusing. It would be more accurate to say that `exported_macros` currently contains only macros that have paths.
This PR renames `exported_macros` to `importable_macros`, since these macros can be imported with `use` while others cannot. It also fixes the code above to no longer lint on private `macro` macros, since the `missing_docs` lint should only appear on exported items.
Fixes#57569.
Add support for raw-dylib with stdcall, fastcall functions
Next stage of work for #58713: allow `extern "stdcall"` and `extern "fastcall"` with `#[link(kind = "raw-dylib")]`.
I've deliberately omitted support for vectorcall, as that doesn't currently work, and I wanted to get this out for review. (I haven't really investigated the vectorcall failure much yet, but at first (very cursory) glance it appears that the problem is elsewhere.)
Simply shift the bitcast from the store to the load, so that
we can use the destination type. I'm not sure the bitcast is
really necessary, but keeping it for now.
I'm not really sure what is wrong here, but I was getting load
type mismatches in the debuginfo code (which is the only place
using this function).
Replacing the project_deref() implementation with a generic
load_operand + deref did the trick.
This makes load generation compatible with opaque pointers.
The generation of nontemporal copies still accesses the pointer
element type, as fixing this requires more movement.
Unescaped command-line arguments for Windows
Some Windows commands, expecially `cmd.exe /c`, have unusual quoting requirements which are incompatible with default rules assumed for `.arg()`.
This adds `.unquoted_arg()` to `Command` via Windows `CommandExt` trait.
Fixes#29494
Use #[track_caller] in const panic diagnostics.
This change stops const panic diagnostics from reporting inside #[track_caller] functions by skipping over them.
Change linked tracking issue for more_qualified_paths
This updates the linked tracking issue for the `more_qualified_paths` feature from the implementation PR #80080 to an actual tracking issue #86935.

I haven't added a variant with `last_node_with_lint_attrs` yet, since I didn't see a usecase for this. Also this field is not documented, so I'm wondering how it behaves with command line lints and so on.
