[ownership] Add an additional run of the SemanticARCOpts at the beginning of the perf pipeline.

I left in the run before DestroyHoisting since I believe that DestroyHoisting
depends a bit on SemanticARCOpts running, but at the same time I don't want to
deal with any regressions that may come from moving DestroyHoisting.
