  Log Message:
  -----------
  [mlir][Vector] Fix reordering of floating point adds during lower of `vector.contract`.

Adding the accumulator value after the `vector.contract` changes the
precision of the operation. This makes sure the accumulator is carried
through to `vector.reduce` (and down to LLVM).
