In other backends we've introduced a `GOTSymbol` parameter to `applyFixup` that allows linkers to cache this symbol (see e.g. x86_64.h) . I think that it would be reasonable to do that here too. This should also improve performance, since you can cache the section start symbol (which you should get from `SectionRange`).
