bcca57b1 - [RISCV] Simplify mask operand check in VLOptimizer. NFC (#150373)

[RISCV] Simplify mask operand check in VLOptimizer. NFC (#150373) We don't need to lookup the reg class because the MCInstDesc already gives us this information. With that we can remove some helper methods, and tighten the assert in isCandidate because all pseudos at this stage should be defining virtual registers.
