This makes the difference between selector matching scaling on the ARM Cortex-A9 and not, because the auto-derived `PartialEq` implementation blows out the 32KB I-cache. With this change, there is a 2x improvement in selector matching over sequential when using all 8 cores. (More work needs to be done; this is a start.) r? any DOM expert Source-Repo: https://github.com/servo/servo Source-Revision: c3d242544e809aca945cf0ca6c2bf0f45ce6a602
