  Changed paths:
    M llvm/lib/Target/RISCV/RISCVTargetTransformInfo.cpp
    M llvm/test/Analysis/CostModel/RISCV/cast.ll

  Log Message:
  [RISCV] Add cost model for mask vector extend and truncate instruction.

As extending from or truncating to mask vector do not use the same instructions as the normal cast, this path changed it to 2 which is the number of instructions we used.
