For performance, don't initialize SparseRep data array to 0.
* Sparse.h (SparseRep (octave_idx_type nr, octave_idx_type nc, octave_idx_type nz = 0)):
Don't use aggregate initialization of array d. It is not necessary since valid elements
are controlled by r and c indices and will be set when an actual value is assigned.
