For the most part, the macro actually worked with _ slugs, but the prefix_something -> prefix::something
conversion was not implemented.
We don't want to accept - slugs for consistency reasons.
We thus error if a name is found with - inside.
This ensures a consistent style.
Having to replace - with _ (and vice versa) makes the slugs less greppable
and thus constitutes a contributor roadblock.
Result of running this repeatedly up until reaching a fixpoint:
find compiler/rustc_error_messages/locales/en-US/ -type f -exec sed -i 's/\(.+\)-\(.*\)=/\1_\2=/' {} \;
Plus some fixes to update usages of slugs leading with -.

errors: don't fail on broken primary translations
If a primary bundle doesn't contain a message then the fallback bundle is used. However, if the primary bundle's message is broken (e.g. it refers to a interpolated variable that the compiler isn't providing) then this would just result in a compiler panic. While there aren't any primary bundles right now, this is the type of issue that could come up once translation is further along.
r? ```@compiler-errors``` (since this comes out of a in-person discussion we had at RustConf)
Generalize trait object generic param check to aliases.
The current algorithm only checks that `Self` does not appear in defaults for traits. This is not sufficient for trait aliases.
This PR moves the check to trait object elaboration, which sees through trait aliases.

passes: load `defined_lib_features` query less
Hopefully addresses the perf regressions from #99212 (see #99905).
Re-structure the stability checks for library features to avoid calling `defined_lib_features` for any more crates than necessary for each of the implications or local feature attributes that need validation.

Update to LLVM 15
For preliminary testing. Some LLVM 15 compatibility fixes were applied separately in #99512.
Release timeline:
* LLVM 15 branched on Jul 26.
* The final LLVM 15.0.0 release is scheduled for Sep 6.
* Current nightly (1.65.0) is scheduled for Nov 3.
Changes in this PR (apart from the LLVM update):
* Pass `--set llvm.allow-old-toolchain` for many Docker images. LLVM 16 will require GCC >= 7.1, while LLVM 15 still allows older compilers with an option. Specify the option for builders still using GCC 5.4. #95026 updated some of the used toolchains, but not all.
* Use the `+atomics-32` target feature for thumbv6m.
* Explicitly link libatomic when cross-compiling LLVM to 32-bit target.
* Explicitly disable zstd support, to avoid libzstd.so dependency.
New LLVM patches ([commits](https://github.com/rust-lang/llvm-project/commits/rustc/15.0-2022-08-09)):
* [rust-only] Fix ICE with GCC 5.4 (15be58d7f0)

Stringify non-shorthand visibility correctly
This makes `stringify!(pub(in crate))` evaluate to `pub(in crate)` rather than `pub(crate)`, matching the behavior before the `crate` shorthand was removed. Further, this changes `stringify!(pub(in super))` to evaluate to `pub(in super)` rather than the current `pub(super)`. If the latter is not desired (it is _technically_ breaking), it can be undone.

Fix flags when using clang as linker for Fuchsia
Don't add C runtime or set dynamic linker when linking with clang for
Fuchsia. Clang already does this for us.
Use `&mut Diagnostic` instead of `&mut DiagnosticBuilder` unless needed
This seems to be the established convention (02ff9e0) when `DiagnosticBuilder` was first added. I am guilty of introducing some of these.
Remove duplicated temporaries creating during box derefs elaboration
Temporaries created with `MirPatch::new_temp` will be declared after
patch application. Remove manually created duplicate declarations.
Removing duplicates exposes another issue. Visitor elaborates
terminator twice and attempts to access new, but not yet available,
local declarations. Remove duplicated call to `visit_terminator`.
Extracted from #99946.
Determine match_has_guard from candidates instead of looking up thir table again
Currently looking through mir build of matches because of interest in deref patterns. Finding some micro-optimizable things.
Check if enum from foreign crate has any non exhaustive variants when attempting a cast
Fixes#91161
As stated in the issue, this will require a crater run as it might break other people's stuff.
Keep going if normalized projection has unevaluated consts in `QueryNormalizer`
#100312 was the wrong approach, I think this is the right one.
When normalizing a type, if we see that it's a projection, we currently defer to `tcx.normalize_projection_ty`, which normalizes the projections away but doesn't touch the unevaluated constants. So now we just continue to fold the type if it has unevaluated constants so we make sure to evaluate those too, if we can.

Currently it's reported as either `TraitItem` or `ImplItem`. This commit
changes it to `AssocItem`, because having the report match the type name
is (a) consistent with other types, and (b) the trait/impl split isn't
that important here.
This commit:
- Adds a comment explaining which `visit_*` methods should be
implemented.
- Adds and removes some `visit_*` methods accordingly, improving
coverage, and avoiding some double counting.
Add support for link-flavor rust-lld for macOS
Also refactor iOS, watchOS and tvOS common code.
The ``-arch`` argument was moved to the ``apple_base`` module instead of the target definitions for macOS.
As ld64 requires ``-syslibroot`` to be passed, ``add_apple_sdk`` was modified accordingly.
