We default to 1 here since we want to behave like a sequential compiler for now. This’ll likely be adjusted in the future. Note that -Zthreads=0 is the way to get the num_cpus behavior.

This name is kind of confusing: Most unstable options enable something themselves, while this just allows “normal” options to be feature-gated.
