`vundefined` doesn't have corresponding named IR, instead it generates
`poison` value, we already define the `Name` for C intrinsics, so we
don't need the defining name at all.

Subject: [PATCH] [RISCV][NFC] Remove unneeded defining name of `vundefined`
`vundefined` doesn't have corresponding named IR, instead it generates
`poison` value, we already define the `Name` for C intrinsics, so we
don't need the defining name at all.
