  Log Message:
  -----------
  [DAGCombine] Check both forms of a commutative transform

The transform to fold an add into the base of a scatter/gather was only checking to see if the LHS was a splat.  Included test change indicates that splats are not canonicalized to LHS, and that we need to check both sides.
