...sorry, I'd also like to request a bit to be assigned for Zmmul as part of this PR, because I received a request to implement this extension. Zmmul is also a ratified standard extension supported in binutils and LLVM. |

Following on from #109, which added the single-letter extensions. Zifencei is a standard, ratified extension so seems worth a bitmap definition, even though I understand e.g. Linux has reasons for not exposing it.
The motivation here is just to have an assigned bit for all standard extensions I implement, since I now expose this bitmap directly in hardware. Zifencei is the only one missing, so I don't plan to continue to trickle these in.
