  Log Message:
  -----------
  [RISCV] Add test cases for masked load/store with all ones/zeros mask. NFC

These should be removed for all zeros mask or optimized to
unmasked for all ones.

    M llvm/test/CodeGen/RISCV/rvv/masked-store-int.ll

  Log Message:
  -----------
  [DAGCombiner] Use isConstantSplatVectorAllZeros/Ones instead of isBuildVectorAllZeros/Ones in visitMSTORE and visitMLOAD.

This allows us to optimize when the mask is a splat_vector in
addition to build_vector.
