The crypto extension have several shorthand extensions that don't consist of
any extra instructions.
Take zk for example, while the extension would imply zkn, zkr, zkt.
The 3 extensions should also combine back into zk to maintain the canonical
order in isa strings.

Hi Shi-Hua:
Thanks, generally it's LGTM, just a few coding style issues. I've
fixed that and committed this time,
but just let you know where you should update your coding style.
And you could use git clang-format and use /contrib/clang-format
as format file to save
your time to indent that.
