error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md
note: rustc 1.54.0-dev running on x86_64-unknown-linux-gnu
note: compiler flags: -C opt-level=3 -C embed-bitcode=no -C incremental --crate-type lib
note: some of the compiler flags provided by cargo are hidden
query stack during panic:
#0 [evaluate_obligation] evaluating trait selection obligation `quote::Tokens: std::marker::Unpin`
#1 [is_unpin_raw] computing whether `quote::Tokens` is `Unpin`
end of query stack
error: aborting due to previous error
error: could not compile `syn`
To learn more, run the command again with --verbose.
```
I've left in the panic and ICE following the pretty error, so that we still have all of the debug information available in a bug report.
This message can be reproduced by cloning the repository `https://github.com/Aaron1011/syn-crash`, and running the following shell script (with a `rustup override` set in the directory):
```
set -xe
cargo clean -p syn
cargo clean --release -p syn
git checkout minimize
cargo build --release -j 1
git checkout minimize-change
cargo build --release -j 1
```

Add primary marker on codegen unit to take charge of main_wrapper for non-local cases.
Rollup merge of #85038 - GuillaumeGomez:dont-stop-first-rustdoc-gui-failure, r=Mark-Simulacrum
Don't stop running rustdoc-gui tests at first failure
I just realized that before this PR, the rustdoc-gui test suite was stopping at the first failure, which isn't very convenient. All tests are now running and if one failed, it returns an error at the end once all tests have run.
