* include Macros.h much earlier: since it takes care of the alignment platform detection, it is needed before we do the vectorization stuff in Eigen/Core !!
* kill EIGEN_DONT_ALIGN_HEAP option (one should use EIGEN_DONT_ALIGN)
* rename EIGEN_DONT_ALIGN_STACK to EIGEN_DONT_ALIGN_STATICALLY. hope it's a better name.
