[PATCH] RISC-V: Check register numbers for vector whole register op

cc Andrew, Palmer and Kito. If I remember correctly, we already discussed
these changes in many patches, github issues and other threads, and then
decided not to do these constraint checks for vectors because these checks
will break many things, like dv testing projects.
Thanks
Nelson
