./x.py test src/test/ui --bless
./x.py test src/test/ui --compare-mode nll
Note that `test src/test/* --stage N` does NOT depend on `build src/rustc --stage N`;

Execute tool tests with a tool name argument:
./x.py test tidy
If no arguments are passed then the complete artifacts for that stage are
compiled and tested.
