  Changed paths:
    M mlir/lib/ExecutionEngine/CudaRuntimeWrappers.cpp
    A mlir/test/Integration/Dialect/SparseTensor/GPU/CUDA/sm80-lt/sparse-matmul-2-4-prune.mlir

  Log Message:
  [mlir][sparse][gpu][nvidia] add pruning step and check to 2:4 matrix multiplication

(1) without the check, the results may silently be wrong, so check is needed
(2) add pruning step to guarantee 2:4 property

Note, in the longer run, we may want to split out the pruning step somehow,
or make it optional.
