Use arenas to avoid Lrc in queries #2
The `Remove subtle Default impl for Value` makes the compilation stop due earlier due to cycle errors, since there's no longer a default value to continue the compilation with.
Based on https://github.com/rust-lang/rust/pull/59540.
syntax: Continue refactoring literals
A follow up to https://github.com/rust-lang/rust/pull/60679.
a2fd002bd5: Similarly to `EscapeError`, literal parsing now produces a `LitError`.
This way we can get rid of `diag: Option<(Span, &Handler)>` in interfaces while leaving attr/mod alone.
d9516d1120: Gathers all components of a literal token in a single struct.
librustc_errors: Remove unused annotation style `OldSchoolNoteText`
I could not find any references to it and the `snippet` module does not
seem to be exported publicly, so I think it can be safely removed.
This was originally removed in 17bd76a51 and I'm not sure why it is still there.
Revert "Add implementations of last in terms of next_back on a bunch of DoubleEndedIterators."
This changed observable behavior for several iterator types.

Solaris CI: Build with dilos2 stable
dilos2-testing has problems since the last repository update, so get the packages from dilos2 stable.
Fixes#61022.
Disable LLVM/debug assertions in gnu-full-bootstrap
This builder already is very close to the 2 hour mark and the debug
assertions aren't really buying us anything over what all the other
containers are enabling, so let's disable them for this slow builder.
Make -Zemit-artifact-notifications also emit the artifact type
This is easier for tooling to handle than trying to reverse-engineer the type from the filename extension. The field name and value is intended to reflect the `--emit` command-line option.

Bump compiler-builtins to 0.1.15
This commit bumps the `compiler-builtins` dependency to 0.1.15 which
expects to have the source for `compiler-rt` provided externally if the
`c` feature is enabled. This then plumbs through the necessary support
in the build system to ensure that if the `llvm-project` directory is
checked out and present that we enable the `c` feature of
`compiler-builtins` and compile in all the C intrinsics.
Add match arm scopes and other scope fixes
* Add drop and lint scopes for match arms.
* Lint attributes are now respected on match arms.
* Make sure we emit a StorageDead if we diverge when initializing a temporary.
* Adjust MIR pretty printing of scopes for locals.
* Don't generate duplicate lint scopes for `let statements`.
* Add some previously missing fake borrows for matches.

Simplify use of keyword symbols
They mirror non-keyword symbols now (see https://github.com/rust-lang/rust/pull/60630).
`keywords::MyKeyword.name()` -> `kw::MyKeyword`
`keywords::MyKeyword.ident()` -> `Ident::with_empty_ctxt(kw::MyKeyword)` (not common)
`keywords::Invalid.ident()` -> `Ident::invalid()` (more common)
Keywords are simply `Symbol` constants now, the `Keyword` struct is eliminated.
This means `kw::MyKeyword` can now be used in `match` in particular.
