It seems like the community is quickly converging on just using the ISA string with Zmmul, and not using no-div. While being compatible with the GNU tools is nice, if they are planning on dropping support for no-div soonish then we probably shouldn't add support for it. IMO, Zmmul should be a separate patch and presumably (at the moment) be gated by `-menable-experimental-extensions`.
