Delete obsolete code

Remove outer product computation code from CompressedRowSparseMatrix.
In the process also remove the crsb_cols and crsb_rows vectors from
the matrix, which were added to carry the block sparsity of the matrix
so that the outer product could be computed fast.

InnerProductComputer and its reliance on BlockSparseMatrix has
rendered all of this code moot.
