The same check doesn't work with PETSc 3.0 because of changes to MatInfo.

The check is not pretty so we should find a better solution if this 
function is required. There is a PETSc function 
MatGetSeqNonzeroStructure which may help, but I haven't had time to look 
at it.

Why is the function PETScMatrix::sameNonzeroPattern required? It's not 
implemented for all backends.
