MatProduct: need to check symmetry between symbolic and numeric

Suppose we have code:
MatTransposeMatMult(A,B,MAT_INITIAL_MATRIX,fill,C);
MatTransposeMatMult(E,B,MAT_REUSE_MATRIX,fill,C);

If A

MatProduct: need to check symmetry between symbolic and numeric

Suppose we have code:
MatTransposeMatMult(A,B,MAT_INITIAL_MATRIX,fill,C);
MatTransposeMatMult(E,B,MAT_REUSE_MATRIX,fill,C);

If A is symmetric and E is not, but E has the same nonzero pattern as A, then above code is legitimate.
If we change the MatProductType in MAT_INITIAL_MATRIX from MATPRODUCT_AtB to MATPRODUCT_AB, then
in MAT_REUSE_MATRIX, we need to redo symbolic otherwise C=E^B would be wronlgy computed as C=EB.
