  Log Message:
  -----------
  Revert "[RISCV] Add policy operand for masked compare and vmsbf/vmsif/vmsof IR"

This reverts commit 10fd2822b77e12215b4ea82fc6d0a052961eb9d9.

I have a better implementation for those operations without the
additional policy operand.
masked compare and vmsbf/vmsif/vmsof are always tail agnostic so we could
assume undef maskedoff is mask agnostic.

  Log Message:
  -----------
  [RISCV] Use maskedoff to decide mask policy for masked compare and vmsbf/vmsif/vmsof.

masked compare and vmsbf/vmsif/vmsof are always tail agnostic, we could
check maskedoff value to decide mask policy rather than have a addtional
policy operand.
