296d24be4d bug #1381: fix sparse.diagonal() used as a rvalue. 
The problem was that is "sparse" is not const, then sparse.diagonal() must have the
LValueBit flag meaning that sparse.diagonal().coeff(i) must returns a const reference,
const Scalar&. However, sparse::coeff() cannot returns a reference for a non-existing
zero coefficient. The trick is to return a reference to a local member of
evaluator<SparseMatrix>.

a9232af845 Introduce a variable_or_fixed<N> proxy returned by fix<N>(val) to pass both a compile-time and runtime fallback value in case N means "runtime". 
This mechanism is used by the seq/seqN functions. The proxy object is immediately converted to pure compile-time (as fix<N>) or pure runtime (i.e., an Index) to avoid redundant template instantiations.

87963f441c Fallback to Block<> when possible (Index, all, seq with > increment). 
This is important to take advantage of the optimized implementations (evaluator, products, etc.),
and to support sparse matrices.
