IterativeSolver and UmfPack do not work with MappedSparseMatrix

Version: 3.3 (current stable)
Description
The problem is that in IterativeSolverBase::compute(const MatrixType& A) the address of a temporary object is retrieved. Even worse, the temporary is an unnecessary SparseMatrix copy of the MappedSparseMatrix.
Maybe IterativeSolverBase::mp_matrix should be some kind of Ref<SparseMatrix> object (not supported yet, I guess?) and compute shall accept arbitrary Matrices, which are either copied or mapped into mp_matrix.
NB: The problem was exposed after new unit tests from bug #670 (closed).
