Zilsd, Zclsd and Zcmp are ratified standard extensions which lack bit assignments. I've just appended them to the end.
Note that Zcmop, which is already listed next to the non-Zcmp Zce extensions, is its own extension, not a typo for Zcmp.
For context, I'm considering exposing this bit mask through a custom M-mode CSR on an embedded-class core to list hardware capabilities with finer granularity than
misa, but less complexity than the configuration struct or device tree. I implement the three extensions added by this PR.
