I wonder if a different name than `hybridSymtab` would be more accurate after this step? Then again, I guess hybrid means the combination of arm64ec and arm64, so in that sense I guess "hybrid" still is relevant even if we mean the other one. (I.e. "the other symtab, for the cases when we have two".)
