For CosineKernel and ProductKernel, we should be able to have a separate
code path with BLAS-2 once SparseMatrix x SparseVector merges and BLAS-3 once
SparseMatrix x SparseMatrix merges..Basically refactor blockify from
MatrixFactorizationModel to IndexedRowMatrix...Right now the sparse features
are not in master yet...For Euclidean, RBF and Pearson, even with these changes
merged, I think we still have to stay in BLAS-1
