[PATCH] D140370: [VP][RISCV] Add vp.ctlz/cttz and RISC-V support.

[Yeting Kuo via Phabricator via llvm-commits]

fakepaper56 added a comment.

I think I need to implement the `is_zero_poison` for vp.ctlz/cttz. I missed it because I thought `llvm.ctlz` and `llvm.cttz` have same interfaces as `llvm.ctpop`. I will update the revision soon.
