Does Rocket supports superscalar?

I'm wondering whether Rocket supports superscalar. I see the fetchWidth, decodeWidth, and retireWidth can be modified and the default fetchWidth is 2 when RVC is enabled. So does Rocket support superscalar?

Start by tracing the Rocket configuration points named in the issue: fetchWidth, decodeWidth, retireWidth, and the RVC setting. Check how these widths affect the pipeline, then document whether they establish superscalar support and explain the role of the default fetchWidth value; no file or test is named.
