URL: https://github.com/llvm/llvm-project/commit/c0ef36f16631b263bd871e50ea2d0cbcd330233a DIFF: https://github.com/llvm/llvm-project/commit/c0ef36f16631b263bd871e50ea2d0cbcd330233a.diff LOG: RISCV: Pass instruction and operand index to vectorPseudoHasAllNBitUsers (#219993) Take the user instruction and operand index directly instead of a MachineOperand, so the helper no longer relies on getParent.
