  Log Message:
  -----------
  [mlir] [VectorOps] Framework for progressive lowering of vector.contract

Summary:
Lowers all free/batch dimensions in a vector.contract progressively
into simpler vector.contract operations until a direct vector.reduction
operation is reached. Then lowers 1-D reductions into vector.reduce.

Still TBD:
multi-dimensional contractions that remain after removing all the parallel dims
