  Log Message:
  -----------
  [MLIR] change NVVM.mma.sync to the most useful variant.

Summary:
the .row.col variant turns out to be the popular one, contrary to what I
thought as .row.row. Since .row.col is so prevailing (as I inspect
cuDNN's behavior), I'm going to remove the .row.row support here, which
makes the patch a little bit easier.
