Fix compilation and warning of PARDISO

Fix bug 635: add isCompressed to MappedSparseMatrix for compatibility
Added move support for Matrix and Array.
Added EIGEN_HAVE_RVALUE_REFERENCES define.
Added move unit tests.
Removed superfluous 'inline' declarations in DenseStorage.
Ensure that (potentially aligned) stack objects are passed by reference.
Fix compilation.

The Matrix is required to be mutable but it also needs to be a reference and
temporaries do not bind to non-const references - thus we need a hack and
cast away the constness.
Removed a warning when rvalue references are not unsed.
Move inheritance from Eigen example in stand-alone file.
Also fix a small mistake (Vector3d instead of VectorXd).
