  Changed paths:
    M llvm/lib/Target/RISCV/RISCVISelDAGToDAG.cpp

  Log Message:
  [RISCV] Add assertion of hasVecPolicyOp to catch masked intrinsic without policy operand.

The original code may have incorrect result if there is a masked instruction
without policy operand to make us set its policy to TUMU. The patch adds an
assertion to catch the instruction.
